Dormer Pramet A110 4.60 mm HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

Dormer Pramet A110 4.60 mm HSS ST Straight Shank Long Series Drill DIN 340

Engineered for precision metalworking, this 4.60 mm HSS straight-shank drill from the Dormer Pramet A110 line delivers dependable performance in a wide range of materials. Its DIN 340 straight shank pairs with standard drill chucks and holders, making it a versatile choice for both handheld drills and machine setups.

Key features that matter in real-world drilling:

• 118° conventional point — initiates cuts cleanly, reduces wandering at start, and is easy to re-sharpen when the edge dulls, keeping downtime to a minimum.
• Steam oxide finish — a controlled oxide coating that minimizes friction and helps prevent material from sticking to the cutting edge, contributing to smoother holes and longer edge life.
• Long length series — designed for deeper holes and applications where extended reach is required, reducing the need for extensions or multi-step operations.
• Premium HSS material — capable of drilling through a broad spectrum of metals, including steel, aluminum, and stainless steel, while maintaining strength and edge retention.
• Versatile usage — suitable for both handheld power drills and machine tools, making it a reliable all-rounder in workshops, engineering labs, and fab shops.

This drill is ideal for machinists, metalworkers, and DIY enthusiasts who frequently encounter deeper drilling tasks or who need a dependable tool for mixed-material projects. The 4.60 mm size is a precise choice for creating clean, accurately sized holes in metal workpieces, from thin automotive brackets to thicker structural components.

Why this drill stands out in practice

• Longer reach translates to fewer tool changes when working on recessed or crowded assemblies.
• The combination of a robust HSS core and a user-friendly 118° point improves hole start quality and reduces the need for follow-up deburring.
• The steam oxide finish lowers sticking and heat buildup, helping maintain edge integrity during longer drilling sessions.
• DIN 340 compatibility ensures predictable performance across a wide range of drilling machines and chucks.

Practical tips for optimal performance

• Use light lubrication or cutting oil to further reduce heat and extend cutting edge life, especially when drilling stainless steel or thick materials.
• Start with a gentle pilot hole if working in harder metals to guide the drill and prevent wandering.
• Match the feed rate to the material: slower feed for harder metals, moderate feed for aluminum and softer steels to achieve a clean, true hole.
• Inspect the edge periodically and re-sharpen as needed to preserve accuracy and hole quality over time.
