Dormer Pramet A101 4.80 mm HSS ST STRAIGHT SHANK LEFT HAND JOBBER DRILL DIN 338

The Dormer Pramet A101 4.80 mm HSS straight-shank left-hand jobber drill is a versatile twist drill designed for reliable metal drilling across steel, aluminium, and stainless steel. With a 4.8 mm diameter and DIN 338 compatibility, it fits standard chucks and holders, making it a practical choice for engineers, machinists, tradespeople, and hobbyists who work with counter-rotating or CCW spindle setups.

The left-hand design suits spindles that rotate counter-clockwise, enabling controlled hole starts and stable cutting in demanding work. The 118-degree conventional point provides a strong, self-centering tip that starts holes cleanly and is easy to re-grind for extended tool life. The steam oxide finish reduces material sticking to the edge and supports smoother chip flow for cleaner holes and less downtime.

• 118° Conventional Point: Provides a strong, self-centering tip that starts holes accurately and is easy to re-grind, helping maintain precision over time.
• Steam Oxide Finish: Minimizes sticking of workpiece material to the cutting edge and improves chip evacuation for smoother, more reliable cutting.
• Left-Hand Spiral Flute: Designed for spindles that rotate counter-clockwise, offering better control and stability in CCW machining setups.

This drill delivers dependable performance across common metals with a straightforward, user-friendly design. Its DIN 338 straight shank ensures quick, secure tool changes, while the combination of a robust HSS material and a specialized geometry helps you achieve consistent hole quality, reduce rework, and keep projects moving efficiently.
