I have a number of holes to make all the same diameter, what can you offer?


Hi Tim,
It depends on the amount of work you are doing, material etc…

  • If you are doing a range of diameters close to one another i’d suggest the Walter D14140 indexible insert drill where one body can do a range of sizes (limited by the body size).

  • If you are doing large diameters 20mm+ but more holes of a specific size i’d suggest a ARNO AKB drill. The productivity will show substantial improvements over most other brands.


    • If you are doing one size of hole 20mm and below i’d recommend the Dormer Hydra Drill. It’s uses a solid carbide drilling head, which can be replaced without removing the tool from the machine and have impressive cutting data as this video illustrates.

Material Type: Alloy Steel, Hardened and tempered steel (AMG 1.5)
