The Dormer A200 HSS Centre Drill is a specialized machining tool ideal for machinists and engineers who need to create precise starting points for turning operations between centres. It provides exceptional stability and accuracy when centering parts, though users should note that as an HSS (High-Speed Steel) tool, it requires proper cooling and feed management to maintain its edge on hardened materials.

The 60 degree included angle represents the profile of the countersink, which is the standard geometry for supporting a component on a lathe tailstock centre.
No, this tool is intended for use in rigid setups like lathes or milling machines where precise alignment is guaranteed.
It is made from High-Speed Steel (HSS), which provides durability for drilling into a variety of ferrous and non-ferrous metals.
DIN 333A is the industrial specification for centre drills, ensuring the drill geometry, length, and diameter meet international compatibility standards.
Select the drill based on the diameter of the component being machined and the size of the tailstock centre you intend to use.
Check alignment of the tailstock and ensure the feed rate is not too aggressive at the moment of contact.
Increase the flow of cutting lubricant and verify that the drill speed is appropriate for the workpiece material.
Proper setup involves ensuring the tailstock or chuck alignment is precise, as any run-out will cause the centre drill to deflect. Always use cutting fluid or oil when drilling to minimize heat build-up and chip welding. To maintain the tool, store it in a dry, organized drill block to protect the delicate tip. If the tip shows signs of dulling, avoid attempting to manually regrind the geometry, as this will compromise the DIN 333A specification accuracy.
