Reducing cost per hole in deep-hole drilling

The cheapest tool rarely produces the cheapest hole. In deep-hole drilling, cost per hole — not tool price — is the number that matters, and it’s driven by tool life, downtime and rework. Here’s where the savings actually come from.

Tool life, not tool price

A tool that costs more but lasts twice as long and drills faster wins on cost per hole. Specifying the right grade, geometry and coating for your material is the biggest single lever.

In-house resharpening

Gundrills are resharpenable. Sending them out means downtime and logistics; doing it in-house with a resharpening machine keeps production moving and lowers cost per regrind.

Coolant and process

Correct coolant pressure and cutting data prevent premature wear, breakage and scrapped parts. This is exactly what our application engineers optimise on your machine.

The takeaway

Buying on tool price alone usually costs more per hole. Buying on specified performance — and keeping tools maintained in-house — is how the cost actually comes down. Talk to us about your deep-hole application.
