Two-piece assembling shank impact drills in DIN 338 metric and ANSI B.94.11M inch series. The assembling hex-shank design allows the drill body to be replaced while the shank stays in the chuck — a cost-saving format for high-volume impact drilling in metal and wood. Factory-direct from a 20-year precision-tools manufacturer with ISO 9001 / 14001 / 45001 triple-system certification.

Manufactured to DIN 338 and ANSI B.94.11M in an ISO 9001 / 14001 / 45001 triple-certified facility — every drill is inspected before packing.
The drill body assembles onto the hex shank; when the body wears, you replace only the body instead of the whole tool.
The range is split into DIN 338 metric sizes and ANSI B.94.11M inch sizes — both listed in the matrix below.
