For steel and cast iron components, users should select the WTX deep hole drill type UNI, while the WTX deep hole drill type ALU is the choice for aluminium parts. Both drills share common features, such as the 135° point angle and straight cutting edge that helps reduce cutting forces. A key feature is the use of four guide lands (six on the ALU drills) that help maintain alignment and accuracy to h7.
For improved swarf clearance and performance, the drills, which are designed to provide an alternative to gun-drilling, also feature polished flutes and through-tool coolant.
