Dormer Pramet A110 3/32 Inch HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

When deep, precise holes are required in metalworking, the Dormer Pramet A110 3/32 inch long-series drill is engineered to perform with consistency across steel, aluminium, and stainless steel. The 118° conventional point delivers an authoritative start, minimizes wandering, and is easy to re-grind for extended life. Coupled with a steam-oxide finish, this drill maintains a clean cutting edge by reducing the tendency for workpiece material to stick to the bit during entry and progression.

At a glance, the A110 long-series drill features a straight shank compatible with standard chucks and drill presses, a 3/32" (0.0938") diameter, an overall length of 95 mm, and a flute length of 62 mm, all manufactured to the DIN 340 standard. Its design is explicitly tailored for extended reach, enabling 6xD drilling without pecking in steel, making it ideal for deep holes and high-precision work where access is limited.

Why choose this long-series drill?

• Deep-hole capability: Long length is purpose-built for reaching through thick workpieces and into recessed areas without sacrificing rigidity.
• Reliable start and wear resistance: The 118° point reduces walking on entry and, with the steam-tempered HSS, sustains cutting efficiency through extended use.
• Versatility across metals: Suitable for drilling steel, aluminium, and stainless steel, making it a pragmatic choice for mixed-material projects and shop fleets.
• Universal compatibility: Straight shank ensures a secure grip in common hand-held and machine drills, enabling both portable and bench-top operations.

Practical usage tips

• Use light cutting fluid or coolant when drilling steel to manage heat and extend edge life; maintain steady feed to avoid deflection on deep holes.
• Secure the workpiece firmly and choose a slower startSpeed to minimize chatter, especially in materials prone to grabbing.
• Re-sharpen the 118° point as needed to preserve starting accuracy and hole quality.
