Dormer Pramet A412 M3 HSS ST STRAIGHT SHANK STEP 90 DEG SHORT SERIES (X2.5D) DRILL

The Dormer Pramet A412 M3 HSS straight shank drill is designed to create chamfered clearance holes for standard metric threads. It features a 118° pilot with a 90° chamfer to guide drilling to the correct clearance diameter and depth, helping you achieve consistent thread engagement.

Constructed from premium high-speed steel, this short-series drill handles a range of materials—from steel and aluminium to stainless steel. The steam oxide finish minimizes material sticking to the cutting edge, promoting cleaner holes and clearer chips. Its straight shank and versatility make it suitable for use in both CNC and conventional machines.

• Exact chamfered clearance holes for metric threads: The 118° pilot with a 90° chamfer guides drilling to the precise clearance diameter and depth required for standard metric threads, ensuring a ready-to-tap hole.
• Steam oxide finish for reduced sticking: The oxide coating helps prevent workpiece material from bonding to the cutting edge, delivering cleaner holes and smoother chip flow for consistent results.
• Premium HSS for versatile use: High-speed steel provides reliable performance across a variety of materials, and the drill is suitable for both CNC and conventional machines, making it a flexible choice in busy workshops.

This drill streamlines threading prep by delivering accurate, repeatable clearance holes, reducing the need for rework and material waste. With its robust HSS construction, compatible finish, and broad material and machine compatibility, it supports efficient workflows in both production settings and hands-on projects.
