About this tool

The Sealey Worksafe HSS Twist Drill Bit Ø8.5mm offers a specialist intermediate diameter for precision large-hole applications. Supplied as a single drill bit, the 8.5mm size is frequently required for pilot holes before tapping M10 and M12 threads, reaming operations, and applications where standard 8mm or 9mm sizes don't provide the exact clearance needed. This size is particularly valuable in heavy engineering, automotive repair, and machinery maintenance where specific tolerances are critical for proper thread formation and component assembly. Features and Benefits: • 8.5mm diameter bridges medium and large sizes • Ideal for M10/M12 tapping pilot holes • Single pack for specialist engineering needs • HSS construction ensures precision through thick materials • Perfect for heavy engineering and automotive applications Specifications: Brand: Sealey Size: Ø8.5 x 115mm

How this comparison works

These retailer offers are joined by a checksum-valid barcode. A similar name or model number alone does not create a match.

We rank item prices from low to high. Where a delivery charge is missing, we cannot claim a cheapest delivered total. Taxes, delivery restrictions and checkout promotions should be confirmed with the retailer.

Each retained price carries its source observation date. Withdrawn or explicitly expired offers are excluded. “Reported available” describes the feed observation, not a live checkout check.
