NPORS Abrasive Wheels Hand Held Cut Off Saw Training (N017)
The petrol cut off saw is the loudest, dustiest and least forgiving tool on a groundworks job. It kicks, it runs a disc at high speed inches from the operator's leg, and cutting concrete or stone dry with one is a straightforward way to get silicosis. A day on the saw your gang actually uses.

What makes our N017 Hand Held Cut Off Saw different
About this course
The NPORS N017 Abrasive Wheels Hand Held Cut Off Saw category covers the hand held petrol driven disc saw used across groundworks, highways, utilities, paving and demolition work to cut kerbs, slabs, blocks, paving, pipe, tarmac and steel. It sits alongside the general N301 Abrasive Wheels category and shares its theory about wheel speeds, mounting and guarding, but it is assessed on the machine itself, which is a different proposition in the hand from an angle grinder.
The tool combines every hazard an abrasive wheel has with the weight and power of a two stroke engine. A disc running above its maximum operating speed or damaged in storage can burst. The saw kicks back from the upper front quadrant of the blade, throwing the machine up and back towards the operator, and it does so faster than anybody can react. Cutting concrete, stone, block and paving releases respirable crystalline silica, which causes silicosis and lung cancer, so the machine has a water feed and the water has to be running. Noise, vibration, hot exhausts, fuel handling and the offcut that drops complete the picture.
A day covers the machine properly. Blade types, abrasive and diamond, and matching the blade to the material and the machine, including checking the blade's maximum operating speed. Inspection, storage and the damage that takes a blade out of use. Mounting with the correct flanges and the guard set. Starting the saw safely, including where it may be started and how it is held. Setting up and proving the water supply. Cutting technique: marking, plunge depth, straight cuts, avoiding pinching in a closing cut, and what to do when the blade binds. Then refuelling, shutting down, slurry management and leaving the work area safe.
- The machine: two stroke engine, controls, guard, arbor and flanges, water feed and the pre use checks that go with each
- Blade types: bonded abrasive and diamond, matching the blade to the material and the machine, and reading the maximum operating speed
- Blade handling, storage and inspection, the damage that makes a blade unfit to fit, and mounting the blade correctly with the right flanges and the guard set before start up
- Starting the saw safely, stance and grip, and the kickback quadrant and how to stay out of the line of the machine
- Water suppression: connecting a supply, proving flow at the blade, slurry management and why dry cutting is not an option on silica bearing material
- Fuel handling, noise, hand arm vibration, PPE, and duties under the Health and Safety at Work etc. Act 1974, PUWER 1998 regulation 9 and COSHH
How completing this course helps you
- The NPORS N017 Abrasive Wheels Hand Held Cut Off Saw category, registered with NPORS and recognised nationally
- An NPORS Red Trained Operator card, or a Blue Competent Operator card where you hold the relevant NVQ, carrying the CSCS logo while your CITB Health, Safety and Environment test is in date
- Operators who will not start a cut in concrete or stone without water running at the blade
- Evidence of the training PUWER regulation 9 requires for anybody using an abrasive wheel
Who should attend?
Groundworks and civils gangs, highways and surfacing crews, utilities and drainage teams, paving and hard landscaping contractors, demolition and refurbishment crews, rail and airport maintenance teams, and plant hire staff who demonstrate saws. It is one of the most commonly used tools on a groundworks job and one of the most commonly used without training, which is why NPORS allow six candidates and most gangs go through together.
Entry requirements. You should be at least eighteen, physically fit enough to control a heavy powered saw at low level and in awkward positions, and able to follow spoken and written English well enough for the theory test, though an interpreter or a reader can be arranged on request. No prior card is required. Because of the dust exposure, your employer should have arranged face fit testing for anybody who will wear tight fitting respiratory protection, and we will raise that at enquiry along with the water supply arrangements for the practical. For the version of the card that carries the CSCS logo you need a CITB Health, Safety and Environment test pass at Operatives level taken within the last two years, which we book for you.

- HSE guidance on abrasive wheels following the repeal of the Abrasive Wheels Regulations 1970
- Machine components: engine, controls, guard, arbor, flanges and the water feed
- Bonded abrasive and diamond blades, matching blade to material and machine, and maximum operating speed
- Blade handling, storage, inspection and rejection criteria
- Mounting, flanges, guard setting and the run up procedure
- Kickback: the upper quadrant of the blade, stance, grip and the correct response when the blade binds
- Respirable crystalline silica, water suppression and slurry, noise, hand arm vibration, fuel handling and PPE
On the saw
- Pre use checks of the saw, guard, arbor, flanges, water feed and fuel system
- Selecting and inspecting the correct blade for the material and the machine
- Fitting the blade with the correct flanges and setting the guard
- Connecting the water supply and proving flow at the blade before cutting
- Starting the saw safely and adopting the correct stance and grip
- Cutting kerb, slab, block or steel to a marked line, controlling depth and avoiding a pinched blade
- Refuelling, shutting down, managing slurry and leaving the machine and the area safe
Method of assessment
How the N017 abrasive wheels hand held cut off saw test works
NPORS assess the category by theory test and practical test. The practical is carried out with water suppression running, on material that behaves like the material your gang cuts.
1. Enquiry and group
Tell us how many people, where, what saws and blades they use, and what water supply is available. Six sit the course with one instructor. We quote per group.
2. Pre course check
We confirm the machines and water arrangements for the practical, check that respiratory protection and face fit arrangements are in place, agree whether you need the CSCS logo version of the card, book the CITB test where it applies, and take the details NPORS need.
3. Training
Classroom on blades, speeds, kickback and dust, then practical cutting with water running. On your own site we use your saws and your material.
4. Theory test
The NPORS theory test covering legislation and the training duty, machine components, blade types and speeds, inspection, mounting, guarding, kickback and silica.
5. Practical test
You carry out the checks, select, inspect and fit a blade, set the guard, prove the water supply, cut to a marked line under control and shut down safely, assessed against the NPORS test specification.
6. Registration and card
We register the pass with NPORS and apply for your card, carrying the CSCS logo where you hold a current CITB Health, Safety and Environment test.
After the course
The water bottle is not decoration
Every cut off saw on the market has a water feed, and a great many of them are used dry because the bottle is empty, the supply is on the other side of the site or the job was only going to take a minute. Cutting concrete, kerb, block, paving or stone dry releases respirable crystalline silica straight into the operator's breathing zone, and the damage it does is permanent. The training gets operatives to prove flow at the blade before cutting, but the site has to make water easy to get. That usually means a bowser or a pressurised bottle with the gang, not back at the compound.
It is also worth planning how much cutting is really needed. A great deal of hand sawing happens because it is the habit rather than because it is the only option, and reducing the number of cuts, or using a saw with on tool extraction where water is impossible, takes the exposure away rather than managing it.
- N301 Abrasive Wheels for the angle grinder and bench grinder side of the same subject
- N048 Powered Hand Held Breaker for breaking out once the cuts are made
- N304 Cable Avoidance Tool where cutting and breaking happen over buried services
- CITB Health, Safety and Environment test booked with us where the CSCS logo version of the card is needed

Who is coming, and how many
We do not run these to a timetable. The course is built around your people: how experienced they are and how many of them there are, which is what sets the length and the cost. Pick the mix and we will come back with a date and a price.
The course builder needs JavaScript. Without it, tell us how many people and what experience they have and we will price it up.
N017 Hand Held Cut Off Saw FAQs
N017 covers the hand held petrol driven cut off saw specifically, and N301 is the general abrasive wheels category aimed at angle grinders, bench and pedestal grinders and wheel changing. The underlying theory about blade speeds, mounting and guarding is shared, but the machines handle completely differently and they are assessed separately. Gangs that use both need both.
The NPORS test sheet gives a one day novice duration with six candidates and one instructor, and the same maximum of six on a refresher. We confirm the length when we quote.
Not on the NPORS test sheet we work from. N017 shows a novice course and a refresher, each with a maximum of six tests, and no experienced worker figure. Experienced users take the course or the refresher rather than a test only route.
Not on concrete, stone, kerb, block or paving. Those materials release respirable crystalline silica, which causes silicosis and lung cancer, and the water feed is the control. If water genuinely cannot be provided, the job needs a different method or a saw with effective on tool extraction, and that has to be planned before the gang arrives.
Yes. Both are in scope, and choosing between them for the material, checking the blade's maximum operating speed against the machine and inspecting for damage are all part of the day. Tell us what your gangs run so the practical matches.
Contact at the upper front quadrant of the blade, or the blade binding in a closing cut. The saw comes up and back towards the operator, and it happens faster than anybody can react. The defence is stance, grip, cutting position and supporting the material so the cut opens.
Six, with one instructor, which is usually a full gang. Running it at your own site means the crew is only off the job for the day and the practical uses your saws and your material.
An NPORS Red Trained Operator card, or a Blue Competent Operator card where the holder has the relevant NVQ. Either carries the CSCS logo while a CITB Health, Safety and Environment test pass is in date.
NPORS courses are priced per course, not per person. What you are paying for is the instructor, the registered tester and the machine time, so the figure turns on four things: the category, which route your operators need (novice, experienced, conversion or refresher), how many people are coming, and whether we run it on your site or at one of ours. It is also why a squad works out considerably cheaper per head than sending operators out one at a time. Use the course builder on this page: tell it who is coming and it works out how many days the course takes and how many times it has to run, which is what the price is built from. Then ask us and you will get a figure for that exact group rather than a list price with conditions attached.
We run NPORS courses across the UK rather than out of one fixed centre, and for most categories the better answer is that we come to you: your operators are assessed on the machine they will be using anyway, nobody loses a day travelling, and for a group it costs less. If you would rather come to us, we have centres at Trent House in Stoke, Pride Park in Derby, Europa House in Manchester and Kingsway House in Liverpool. Tell us where the work is and we will say honestly which way round makes more sense.
There is no fixed timetable to wait for. NPORS courses here are run to order, which means the dates are built around your programme rather than ours, and a single operator or a full squad can normally be booked in within a couple of weeks. If you have a card about to expire or a start date to hit, say so when you enquire and we will work to it.
