Bosch center drill 2608596295 — ground, 1 piece is a precision ground centre drill designed to make accurate starting points for drilling and lathe operations. Supplied as a single, ready-to-use unit, the tool provides a true concentric entry and sharp cutting edges that reduce runout and help avoid drill walking. Its ground finish enhances dimensional accuracy and repeatability in workshop, metalworking and machining environments.

Advantages

The ground tip delivers improved cutting geometry and a sharper point compared with unground variants, increasing centring accuracy. Supplied as one piece, this centre drill is convenient for immediate use and reduces selection errors. The hardened and precisely machined body supports stable clamping and consistent concentricity, which helps extend the life of following drills and tooling by providing a correct starting bore.

Key specifications

How to use

Secure the centre drill in the appropriate drill chuck or tailstock arbor and ensure correct alignment with the workpiece axis. Apply light feed pressure to establish the initial centre dimple, then withdraw and proceed with the intended drill or lathe operation using the centre mark as the accurate starting point. Maintain recommended speeds and cutting parameters for the workpiece material and retract the tool periodically if needed to clear chips.

Recommendations

Use appropriate clamping and alignment procedures to maximize concentricity. For best results, match cutting speed and feed rate to the material being machined, and inspect the ground tip for wear before use. Replace the centre drill if the ground edge becomes rounded or chipped to preserve accuracy of subsequent drilling.
