The Bosch 2 608 597 773 spiral cutting drill bit is a 3.5 mm diameter tool engineered for precision drilling tasks. Designed for use with standard drills and rotary hammers, this spiral cutting bit offers consistent chip evacuation and straight drilling performance in a range of common materials. The geometry of the flute and cutting lip supports accurate hole positioning and stable rotation at moderate speeds.

Advantages

This 3.5 mm spiral cutting drill bit provides precise hole formation with reliable centring and minimal walking at startup. The spiral flute design improves chip removal to reduce heat buildup and prevent clogging during extended use. Manufactured to Bosch quality standards, the bit is balanced for smooth rotation and consistent cutting action across its length, supporting repeatable results in series drilling.

How to use

Select the appropriate drill speed and secure the bit in a compatible chuck or holder. Mark the drilling point and, if necessary, use a centre punch to improve initial positioning. Start drilling at low speed to establish the hole, then increase speed as stability is achieved. Apply steady feed pressure, allowing the spiral flute to evacuate chips; withdraw periodically for cleaning when drilling deep holes. After use, clear debris from the flute and store the bit dry to maintain performance.

Recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. Match drill speed and feed rate to the work material to avoid overheating. For hard materials or precision-critical tasks, consider pilot holes and appropriate lubrication or cooling when recommended for the material.
