Dormer Pramet A110 17/64 Inch HSS ST STRAIGHT SHANK LONG SERIES DRILL DIN 340

The Dormer Pramet A110 17/64 Inch HSS ST Straight Shank Long Series Drill DIN 340 is built for precision, reach, and reliability in demanding drilling tasks. Designed to punch deeper holes with clean chips, this drill balances robust performance with practical versatility for both shop floor and field work.

• 118° conventional point delivers a strong, starting tip that resists walking and re-sharpens easily for repeated use, reducing downtime and tooling costs.
• Steam oxide finish minimizes material sticking to the cutting edge, promoting smoother chip flow and fewer pullouts during long holes.
• Long length series provides extra reach for through-holes, blind holes in recessed areas, and applications where you need greater flute length without compromising rigidity.
• Premium HSS material stands up to drilling various metals, including steel, aluminum, and stainless steel, offering dependable performance across mixed-material work.
• Straight shank ensures broad compatibility with a wide range of chucks and holders in both handheld and machine setups.
• DIN 340 designation guarantees a consistent size standard for interchangeable tooling, making it a reliable choice in mixed tooling environments.

Real-world use cases:

• Fabrication and maintenance tasks that require deeper holes in steel frames or structural components without swapping to a longer, less rigid tool.
• Automotive and machinery assembly where extended reach can simplify drilling in tight or awkward spaces.
• Prototype and production environments that benefit from a single, dependable drill capable of handling steel, stainless steel, and aluminum with minimal tool changes.

Why this drill stands out:

• Unlike generic high-speed steel bits, the A110’s geometry and finish are optimized for consistent performance across materials and repeated re-sharpening, extending tool life.
• The combination of long reach, sturdy straight shank, and DIN 340 compliance makes it a practical, long-term addition to any metalworking toolkit.

Practical tips for best results:

• Use proper lubrication and steady feeds to prevent heat buildup, especially in stainless steel and other harder alloys.
• Spot drill or pilot into tougher materials to reduce wandering during initial contact.
• Regularly inspect and re-sharpen the tip to maintain the 118° geometry for clean starts and accurate hole diameters.
• Store with protective caps or cases to preserve the steam oxide finish and edge integrity between jobs.
