Dormer Pramet A976 4.50 mm HSS-E HIGH PERF MULT-APP STRAIGHT SHANK EXTRA LONG SERIES (1) DRILL DIN 1869 / 1

The Dormer Pramet A976 4.50 mm HSS-E Extra Long PFX drill is engineered for serious deep‑hole performance. With a 130° point angle and a straight shank that meets DIN 1869/1, this tool delivers confident self‑centering and a smoother start, reducing the push force required to begin cutting.

Designed for long reach and reliability, this drill combines a bright finish, a parabolic flute design, and premium HSS‑E chemistry to handle a range of materials with consistent results. The parabolic geometry optimizes chip evacuation and cutting forces when drilling very deep holes in a single pass, helping maintain straightness and finish quality throughout the hole.

• Diameter: 4.50 mm; Overall length (OAL): 185 mm; Flute length: 125 mm; DIN 1869/1 compliant
• 130° point angle for self‑centering and reduced entry force
• HSS‑E cobalt‑based composition for drilling steels, stainless steels, and aluminum
• Extra long length (PFX) with straight shank for extended reach in deep holes
• Bright finish minimizes material adhesion to the cutting edge, preserving effectiveness
• Parabolic flute design enables drilling very deep holes in a single pass (15×D guidance in steel) with improved swarf control

Ideal for machinists, fabricators, and maintenance professionals who frequently encounter long through‑holes, engine blocks, or recessed pockets. When you need dependable depth, consistent hole quality, and the freedom to work without frequent tool changes, the A9764.5X185 delivers the precision and reach you require.

In practice, this drill excels in steel and stainless steel through‑holes, and it also handles aluminum with confidence thanks to its robust HSS‑E core and efficient cutting geometry. If you’ve been restricted by standard drills that clog or wander in long holes, switch to this extra‑long A976 and experience steadier starts, cleaner holes, and fewer tool changes on demanding projects.
