Description
The Dormer Pramet A210 5.00 mm x 12.50 mm HSS centre drill is a metric radius-form tool purpose-built to create precise, protected centre holes on shafts and workpieces. With an 118-degree pilot and concave cone, it starts cleanly and centers securely, helping you hold parts firmly during machining. Its double-ended design and bright finish, paired with premium HSS, make it a versatile choice for drilling across steel, aluminium, and stainless steel on both CNC and conventional machines, in line with DIN 333R specifications.
- Double-ended design for increased productivity: Two cutting ends extend tool life and lower per-hole cost by letting you flip to a fresh edge without changing tools, reducing downtime.
- 118° pilot with concave cone for protected centre holes: Delivers accurate starting guidance and true centering, minimizing drift and improving workholding during subsequent drilling or tapping operations.
- Premium HSS with bright finish for versatile use: Durable high-speed steel handles a range of materials (steel, aluminium, stainless) with a bright finish that reduces material sticking and aids chip clearance in CNC and conventional setups, all conforming to DIN 333R.
Using this centre drill streamlines setups, reduces rework, and delivers consistently true center holes that improve part alignment and overall machining performance from start to finish.
