Twist Drill — Type N short HSS‑E, 8.8 mm, 135° Point Angle, 5% cobalt‑alloyed, DIN 338, Fully Ground

A Twist Drill (Type N, short) designed for precision metal drilling with improved stiffness and suitability for hard materials.

• Short Design for higher drilling stability
• HSS‑E Material with 5% Cobalt for wear resistance
• 135° Point Angle for hard and stainless steels
• Fully Ground shank for excellent runout accuracy
• Conforms to DIN 338 for short twist drills

Higher stability for precise metal drilling

The short execution provides a Short Design that reduces the cantilever length and significantly lowers deflection during operation. This means the bit delivers straighter holes and improved positional accuracy when used in a Drilling Machine or bench setup. For precision work in metal, reduced vibration translates into fewer rejects and faster downstream operations.

Durable HSS‑E composition for tough applications

Made from HSS‑E with 5% Cobalt, the drill retains hardness at elevated temperatures and resists wear when cutting alloyed steels. Cobalt‑alloyed high‑speed steel improves tool life and allows more aggressive cutting parameters on harder materials. This blend is advantageous when drilling stainless steel or other demanding metals where conventional HSS would wear prematurely.

Geometry optimised for hard materials and centering

A 135° Point Angle and Type N normal spiral geometry favour slower entry but superior centring and lower axial forces in hard materials. The geometry reduces chipping at the tip and helps maintain hole quality in thicker or tougher workpieces. For users unfamiliar: the point angle controls penetration and centring, with 135° commonly chosen for steels and stainless applications.

Fully ground shank and conformity to DIN 338

The bit is Fully Ground, meaning the flutes and geometry are created by CNC grinding rather than rolling, resulting in sharper cutting edges and high concentricity. The product conforms to DIN 338 for short twist drills, ensuring consistent dimensions and interchangeability with standard toolholders. Users benefit from predictable fit and performance in professional shop environments.

Intended applications and recommended use

This short Type N twist drill is primarily specified for Drilling for Metal and is suitable for alloyed and unalloyed steel, cast iron, Non‑Ferrous Metals and Plastics under appropriate speeds and lubrication. Its shorter overall length increases stability for handheld or stationary machining. For best results, use cutting fluid and moderate spindle speeds; cooling reduces heat build‑up and extends tool life.
