Drill Bits for Micromot Drills

The term HSS comes from the utilised drill material. High speed steel (HSS) is a high alloy tool steel extremely resistant to wear due to its manufacturing process and is dimensionally stable up to approx. 600°C.

Cutting oil or coolant emulsion should be used as cooling lubricant, when machining steel.

Spirits or petroleum should be used for aluminium.

Normally, plastic and wood can be dry-machined.
