Care Card
A useful care card for CNC bits, holders, and machine-side handling on South African shop floors, written for crews who already know the work.
How Care Card helps on a busy shop week
The Care Card page gives machine-side guidance for looking after CNC bits and holders. It covers handling, storage, and floor use so tooling stays in better condition between setup, cutting, and removal.
The Care Card starts at the spindle, not in the office. It sets out how to handle cutters and holders during fitting, removal, wipe-down, and storage, with notes that suit MDF dust, aluminium chips, humid coastal air, and inland workshop grime. Crews in Johannesburg, Durban, Cape Town, and smaller industrial towns use these checks to reduce edge damage between jobs.
Keep the card near the machine where collets are cleaned and tools are changed. A quick photo of the cutter, holder, and spoilboard condition helps when wear marks, burning, chatter, or chip packing need to be traced later. Short handling notes matter most when one operator hands over a running job to the next shift.
Machine-side checks for cutters
Bit care, holder inspection, and safe machine-side habits all affect tool life and cut quality. Check what needs attention before cutting, clear what builds up during the run, and inspect the tool again before it goes back into storage. Small handling mistakes can lead to chipped edges, run-out, or poor finish on the next sheet or plate.
Use the Care Card alongside notes from the current cut if you need input through the contact form. Include the machine, cutter type, material, and the fault you can see on the part or tool. A short note on the collet nose, holder, or cutting edge condition is usually more useful than a long description.
- Collet cleaned before each tool fit
- Cutting edge checked for chips and resin
- Holder and bit stored dry after use
Storage conditions across South Africa
Near the coast, salt-heavy air can mark holders and steel shanks if they go back wet or dusty. In Gauteng and other dry inland areas, fine dust works into collets, tapers, and drawers, so cleaning intervals often need to be tighter than the manual suggests. The Care Card keeps those differences in view when tools move between machine, bench, cabinet, and courier box.
Power interruptions also affect tooling care, especially when a cutter is left in the spindle after a stopped run. Resin build-up, hot chips, and packed dust are easier to deal with straight after machining than the next morning. For shops cutting board, plastics, or aluminium in mixed batches, the card helps separate cleaning steps by material instead of treating every tool the same way.

What to record on the card
Send the Care Card with machine or tool photos, the cutting stage, and what has already gone wrong. Use a subject line that names the job, machine, or cutter in question.
Write down the bit diameter, coating, holder type, material being cut, and any feed or spindle setting linked to the problem. Add visible signs such as burning, burring, noise, chip welding, or uneven finish on the sheet edge. Those notes make the card useful for the next setup, not just the current issue.
