Dormer Pramet A210 6.30 mm x 16.00 mm HSS METRIC RADIUS FORM CENTRE DRILL DIN 333R

Dormer Pramet A210 centre drill, 6.30 mm x 16.00 mm, is a metric radius-form HSS centre drill designed for precision starting holes in shafts. Built to DIN 333R, it performs reliably on both CNC and conventional machines, making it a versatile choice for engineers, machinists, and workshop teams.

Its 118° pilot and concave cone create protected centre holes that help secure workpieces and improve alignment. The bright finish reduces sticking of workpiece material to the cutting edge, while the double-ended design provides two drilling ends for higher productivity and better value per job. Crafted from premium HSS, it handles a wide range of materials, including steel, aluminium, and stainless steel.

• Double-ended design for increased productivity and economy: Two drilling ends mean fewer tool changes and faster job throughput, reducing downtime and lowering tooling costs in both repetitive and mixed-program operations.
• 118° pilot with concave cone for protected centre holes: Guides accurately into the shaft center to produce clean, protected starts that improve holding strength and reduce runout during machining.
• Premium HSS with bright finish for broad material compatibility: Delivers durable performance across steel, aluminium, and stainless steel, while the bright finish minimizes friction and edge sticking for reliable starts and longer tool life.

This centre drill helps streamline setups, improve hole accuracy, and extend tooling life. The dual ends provide excellent value for busy shops, and its wide material compatibility along with DIN 333R compliance ensure dependable performance in both modern CNC cells and traditional lathes—delivering consistent results and smoother production runs across shaft-centre drilling tasks.
