Dormer Pramet A101 4.00 mm HSS ST STRAIGHT SHANK LEFT HAND JOBBER DRILL DIN 338

The Dormer Pramet A101 4.00 mm HSS Straight Shank Left-Hand Jobber Drill is a compact, versatile drill bit designed for precise metal drilling. With a 4.00 mm diameter and a straight shank conforming to DIN 338, it fits a wide range of chucks and collets for dependable performance in workshops and production environments. The left-hand spiral is tailored for setups where the spindle rotates counter-clockwise, delivering controlled cutting action and predictable results.

• 118° Conventional Point: Provides a strong starting edge that resists walking and is easy to re-sharpen, helping you achieve clean holes and extend bit life.
• Steam Oxide Finish: Reduces friction and helps prevent workpiece material from sticking to the cutting edge, supporting smoother cuts and longer tool life.
• Left-Hand Spiral Flute: Optimized for counter-clockwise spindle rotations, improving chip evacuation and control in compatible machines and setups.

Designed to deliver reliable, consistent performance across common materials—steel, aluminium, and stainless steel—this drill offers sturdy construction, standard DIN 338 compatibility, and a re-sharpenable point for long-term value. Whether in a professional shop or a DIY workspace, it helps you maintain accuracy, reduce downtime, and complete projects with confidence.
