Product Features

●To improve the tools precision and accuracy, YAMAWA adopted a single end design. ●Higher quality center holes can be achieved with the AUCES and AUSDS coated, single end design center hole drill. ●Because of the single end design, the tool length in the holder is constant and the tool projection is constant.

Compared with a double end center hole drill, the accuracy of

the drill part and shank accuracy are improved with a single end

center hole drill.

The position of the tool identification markings is made at the back

of the shank part to avoid clamping at the marking position of the

drill. For higher speeds and higher feeds The drill length (ℓ) is shorter than the conventional double end product. Higher speed, higher feed machining is possible. Conventional item Double-ended type Single-ended type
