The longest clip in the collection, and the only drilling operation: a brake disc drilled through, with the chip evacuation visible from start to exit.
What the clip shows
- Through-drilling a cast iron brake disc
- Chip evacuation and drill exit in frame
- Longer cycle, so heat build-up is visible
Why this insert suits the cut
Drilling is where a brake disc job can stall. Cast iron chips break short if the drill geometry suits the material; if not, they pack the flutes and the drill overheats before the hole is through.
Where this part is used
Drilled brake discs are common on ventilated and two-piece designs. The hole pattern has to repeat across thousands of parts, so tool life matters more than a single fast hole.
What to send with an inquiry
- Hole diameter, depth and pattern count
- Whether the disc is drilled before or after turning
- Coolant-through or external supply
