Dormer Pramet A117 1.90 mm HSS-E STRAIGHT SHANK STUB DRILL DIN 1897

The Dormer Pramet A117 1.90 mm HSS-E straight shank stub drill (DIN 1897) is a precision cutting tool designed for metalworking where small, accurate holes are required. With a straight shank for secure seating in standard chucks and holders, this 1.90 mm drill is ideal for engineers, machinists, fabricators, and hobbyists who need reliable performance in hard materials.

Equipped for difficult tasks, this A117 provides a self-centering 135° split point and a bronze oxide finish that help start holes cleanly, reduce sticking and built-up edge, and deliver consistent hole quality and smoother finishes.

• 135 Degree Split Point: Self-centering tip reduces wandering and lowers the push force required, helping you start holes precisely and maintain alignment for accurate hole size.
• Bronze Oxide Finish: Creates a barrier that resists material sticking to the cutting edge, improving chip flow, reducing built-up edge, and extending tool life.
• Heavy-Duty HSCO Construction: Robust design supports drilling hard materials (including tool steel) with reliable performance and longer service life in demanding applications.

With its 1.90 mm diameter and DIN 1897 straight shank, this drill delivers repeatable, high-quality holes with minimal deflection. The combination of a centering point, anti-stick finish, and rugged construction helps you complete tough drilling tasks faster, reduces rework, and ensures consistent results across jobs. Trustworthy performance in challenging materials makes it a dependable choice for production and repair work.
