Twist Drill — Type N short HSS-G drill bit, Ø 12.9 mm, 135° tip, bright finished

The Twist Drill Type N short variant for Drilling Machines designed for precise metalworking and hard materials such as steel

• Short Design improves Stability and Precision
• 135° Tip Angle suited for Harder Materials
• HSS-G Material for Clean, Accurate Metal Holes
• Fully Ground Shank for High Roundness and Grip
• Conforms to DIN 338 for Short Twist Drills

Precise Material and Cutting Performance for Demanding Metalwork

The short Twist Drill in HSS-G offers a clear advantage when machining metals: the short overall length reduces cantilever action and thus vibration, delivering a truer hole and longer tool life under appropriate conditions. Manufactured with a CNC grind on the flutes, this variant produces very sharp cutting edges and excellent radial runout. For operators working on alloyed and unalloyed steels, cast steel, cast iron and non-ferrous metals, the geometry and 135° tip angle shorten the initial centering phase and reduce burr formation when used with suitable coolant.

Stability and Faster Drilling with Lower Thrust

Short design yields measurable process benefits: reduced deflection allows higher feed rates and better surface finish with less risk of tool breakage during stationary or mobile machine operation. The fully ground shank improves concentricity in the chuck and enhances torque transmission. In many workshop applications this results in up to 40% faster drilling and noticeably lower required thrust compared with conventional HSS variants, making the tool particularly suitable for demanding, repetitive metal drilling tasks where consistency matters.

Where this Tool Excels and How to Use It

Engineered under DIN 338, this Type N short Twist Drill is optimized for drilling in tougher materials and for situations requiring precision rather than deep-hole capability. When used with appropriate clamping, correct spindle speed and cutting fluid, the bit delivers clean, cylindrical holes and extended edge life. The short flute length also simplifies tool handling and reduces the tendency to chatter, which benefits both manual Drilling Machines and light machining centres. Cooling is recommended for prolonged operations to avoid thermal softening.

Recommended Users and Typical Applications

Workshop professionals, maintenance technicians and precision fabricators benefit most from this short Twist Drill from MetavCUT, Standard Line. Its characteristics make it a reliable choice for production runs involving steel, cast materials and hard plastics, where repeatable accuracy and surface quality are priorities. The balanced combination of geometry and material allows use in both stationary and portable Drilling Machines provided adequate support and coolant are available.
