Dormer Pramet A940 5/32 Inch HSS-E HIGH PERF MULT-APP STRAIGHT SHANK LONG SERIES DRILL DIN/ANSI

The Dormer Pramet A940 5/32 Inch HSS-E High Performance Multi-Application Straight Shank Long Series Drill (DIN/ANSI) is engineered to deliver precision, reliability, and deep-hole capability across a range of materials. Built for professionals who demand consistency, this drill redefines efficiency in every hole.

• 130° point: Precisely engineered to self-centre, reducing push force and helping start holes with minimal wandering for cleaner entry.
• Bright finish: A smooth, glare-free edge that minimizes workpiece adhesion and helps produce uniform chip formation.
• Special parabolic flute design: Optimized flute geometry evacuates chips rapidly, enabling extra-deep holes in a single pass without clogging or deflection.
• Premium HSS-E material: Cobalt-enriched high-speed steel for enhanced wear resistance and toughness when drilling steel, stainless steel, and aluminum.
• Long series with straight shank: Extended flute length for deeper drilling paired with a standard straight shank that fits most drill chucks and collets.
• High-performance with H10 tolerance: Delivers consistently high-quality, accurate holes even at higher speeds and feeds, keeping diameter control tight in demanding workpieces.

What makes it uniquely capable is the combination of a precision 130° point with a parabolic flute and cobalt-enriched HSS-E. This synergy reduces heat buildup, improves depth reach, and maintains hole integrity from entry to finish. The result is fewer tool changes, reduced rework, and reliable performance in shop-floor environments where time and accuracy matter.

Ideal for: fabricators, machine shops, automotive and aerospace suppliers, and seasoned DIYers who routinely drill through steel, stainless steel, and aluminum. It’s especially well-suited for through-holes and long-reach drilling tasks where conventional short-flute drills struggle to maintain concentricity or clear chips.

Use-case scenarios: - Through-holes in structural steel components requiring clean, true diameters. - Deep-pocket drilling in aluminum panels where chip evacuation is critical. - Stainless steel fixtures that demand wear resistance and stable hole tolerances under high-speed drilling.

Practical tips: - Select a spindle speed appropriate for the material: for a 5/32" drill in steel, start with a moderate speed and adjust based on chip formation and heat; increase depth gradually to manage heat and maintain edge life. - Use minimal cutting fluid on steel and stainless for cooling and to extend tool life, especially at higher speeds. - Apply steady, even feed pressure; avoid abrupt plunges to preserve the 130° point and prevent wandering. - Ensure the drill is properly secured in a clean, tight chuck or collet to minimize runout and maximize hole concentricity.
