Dormer Pramet A977 7.00 mm HSS-E High-Performance Multi-App Straight Shank Extra Long Drill (DIN 1869) – Set of Two

Designed for professionals who demand precision, reach, and reliability, this 7.00 mm drill from the Dormer Pramet A977 family is built to perform across multiple materials and applications. The combination of an optimized cutting geometry, robust HSS-E composition, and an extra-long form makes it a versatile choice for deep-hole drilling tasks in busy workshops and fabrication benches.

• 130° self-centering point minimizes wandering at entry and reduces push force, helping you start holes cleanly and maintain true alignment from the first cut.
• Bright finish reduces friction and prevents workpiece material from sticking to the cutting edge, promoting smoother chip flow and a cleaner bore.
• Parabolic flute design is engineered for deep-hole drilling, enabling longer holes in a single pass with efficient chip evacuation and reduced heat buildup.
• Premium HSS-E material delivers superior wear resistance and heat tolerance, making it suitable for steel, stainless steel, and aluminum—extending tool life under demanding conditions.
• Extra-long length provides the reach you need for deep pockets, long blind holes, and scenarios where standard drills can’t reach.
• Straight shank with DIN 1869 compatibility ensures easy clamping in common chucks and tool holders for quick, reliable setups.
• Two-drill set offers immediate value for projects requiring multiple holes or back-to-back drilling, keeping your workflow steady and efficient.

Who benefits from the A977 7.0 mm HSS-E Extra-Long Drill

Manufacturers, automotive shops, and metal fabricators who need dependable deep-hole capability will appreciate the A977’s balance of reach, accuracy, and longevity. It excels on thick-wollower aluminum profiles, steel sections, and stainless components where precise hole location and clean exit are essential. This drill’s multi-application design means you can rely on a single tool for a range of materials and hole depths, reducing tool inventory and tool-change time.

Practical guidance for best results

• Use appropriate cutting fluid or coolant for tougher materials to optimize life and finish.
• Start at a conservative feed rate and steady spindle speed; increase gradually while watching chip formation to maintain a clean bore.
• Peck drilling can help evacuate chips in very deep holes; pause occasionally to clear chips without losing pilot alignment.
• Keep the tool sharp and store in a dry environment to preserve the bright finish and edge integrity.

In short, the Dormer Pramet A977 7.00 mm HSS-E Extra-Long Drill is a purpose-built solution for anyone who needs consistent performance in deep-hole drilling across steels, stainless steels, and aluminum. The 2-pack ensures you’re equipped for ongoing projects, delivering reliable starts, deep reach, and durable wear life in a single, streamlined tool.
