I have a large quantity of Carbide stub drill bits.
Those are Co8%, not the cheap stuff you find on eBay.
Buck & Hickman sell these for between £4 (small sizes) and £14.78 (7.4mm) each.
All new, never used.
I'm selling them for £6 for ten, whatever sizes you want. Postage is £1 first class per 10.
I was using one on a 6000rpm mill/drill a last night plunging into steel with no lubricant to a depth of 15mm in a couple of seconds. I made ten of these holes in quick succesion and there was no visible damage to the drill bits at at all, despite it being ridiculously hot.
I have the following sizes:
3.2mm
4mm
6.1mm
7.4mm - 14 left
1/8" - 3 left
Others:
7.4mm, packs of 5 Carbide stub drill bits £2.50
Others, Non-Carbide:
2.4mm fully ground, x10 £3
2.5mm fully ground, x10 £3
3.3mm fully ground x9 £3
4.8mm fully ground x10 £3.50
