Advantages
The Tvardy HSS long 4.0 x 280 mm DIN1869 drill bit offers durable high-speed steel construction that maintains hardness and cutting ability at elevated temperatures typical for metal drilling. Its long geometry provides extended reach for deep or hard-to-access holes while preserving concentricity and straightness.

The design supports efficient chip evacuation in many metal drilling applications when combined with appropriate speeds and lubrication.

How to use
Select a compatible chuck or collet that securely holds a 4.0 mm shank. Clamp the workpiece firmly and, where possible, use a center punch to mark the drilling point. Start at a low speed to establish the hole and then increase RPM according to material and drill diameter, using recommended cutting speeds for HSS in metals. Apply appropriate cutting fluid or lubricant to reduce heat and improve chip evacuation. Use steady axial feed pressure and back the drill periodically on deep holes to clear chips.
Usage recommendations
For best results when drilling steel and harder metals, use cutting fluid, keep spindle speeds within recommended HSS ranges, and avoid excessive feed that can cause breakthrough chipping. Inspect the bit for wear before use and replace when cutting performance or hole quality deteriorates.
