Dormer Pramet A110 7/8 inch HSS Straight Shank Long Series Drill (DIN 340) is engineered for precise, deep-hole drilling in a range of metals. Built for reliability in both hand-held and machine environments, it combines a robust geometry with a finish that keeps your cutting edge clear of built-up material.

Key features that matter in real-world use:

• 118-degree conventional point provides a strong, self-centering starting angle that resists wandering and is straightforward to re-sharpen when needed.
• Steam oxide finish minimizes sticking and chip adhesion, promoting smoother entry and easier cleanup of each hole.
• Long length series delivers extended reach for deep holes and recessed work areas without compromising overall rigidity or stability.
• Premium HSS material offers dependable performance across common metals—steel, aluminum, and stainless steel—while maintaining sharpness over many holes.
• Straight shank design ensures secure clamping in a wide range of chucks and holders, from handheld drills to drill presses and CNC machines.
• DIN 340 compatibility ensures easy integration with standard tooling and fixtures used in professional shops.

Use scenarios where depth and reach are priorities: drilling deep through-thickness steel plates, fabricating automotive or industrial enclosures, or creating precise deep holes in aluminum extrusions. The A110 excels in setups where you need consistent hole quality without frequent tool changes.

Why this drill stands apart: the combination of a resilient 118-degree point, a chip-shedding steam oxide finish, and a long-reach design translates to cleaner starts, steadier feeds, and fewer interruptions during a drilling sequence. This is especially valuable in production environments or DIY projects that demand repeatable results over many holes.

Practical tips for best results: lubricate and cool when drilling steel to extend edge life; begin with a light pecking motion to clear chips on deep holes; maintain steady, moderate feed pressure to reduce deflection; and periodically inspect the point for wear and re-sharpen as needed with proper tooling.

Designed for professionals who value accuracy, durability, and compatibility with existing toolkits, the Dormer Pramet A110 long-series drill is a dependable choice for tackling thicker workpieces and deep-hole tasks with confidence.
