Dormer Pramet A125 4.50 mm x 160 mm HSS ST STRAIGHT SHANK EXTRA LONG SERIES DRILL BS 328

Introducing the Dormer Pramet A125 4.50 mm x 160 mm HSS ST Straight Shank Extra Long Series Drill BS 328 – a purpose-built solution for deep-hole work and reliable metal cutting.

118° conventional point delivers a robust center, reducing wandering on initial bite and ensuring clean, accurate starts. Designed for easy re-grinding, this point geometry helps you refresh the edge in the field, extending tool life without sacrificing performance.

Steam oxide finish minimizes material buildup at the cutting edge, helping chips clear more freely and reducing friction. The result is steadier hole formation, less chatter, and improved hole quality across a range of materials.

Extra long length series (160 mm overall length) provides exceptional reach for drilling very deep holes, pockets, or through-torso applications where standard-length drills can’t reach. It’s a dependable choice when you need access in tight or tall workpieces without sacrificing rigidity.

Premium HSS material covers a broad drilling spectrum, enabling effective performance in steel, aluminium, and stainless steel. With proper speed and lubrication, you can tackle mixed-material projects in a single tool without swapping drills.

Straight shank versatility means compatibility with a wide range of drilling machines, from benchtop and pillar drills to CNC setups. The straight shank delivers solid grip, minimal runout, and consistent hole geometry across applications.

This drill is ideal for machinists, fabricators, and maintenance shops that need precise, deep-hole capability in a compact, dependable package. Use it for drilling into structural steel components, automotive housings, or aluminium assemblies where long reach and robust cutting performance matter.

Key specifications: 4.50 mm diameter x 160 mm overall length, HSS (high-speed steel), straight shank, 118° point, steam oxide finish, BS 328 standard.
