The Bosch 5.5 mm x 93 mm drill bit is a precision-engineered rotary tool designed for accurate drilling in a range of common materials. With a 5.5 mm diameter and an overall length of 93 mm, this bit is suitable for through-holes and blind holes where a moderate depth and precise hole size are required. It is manufactured to Bosch quality standards to provide consistent cutting geometry and stable performance during use.

Advantages

This drill bit offers accurate hole sizing with its 5.5 mm cutting diameter and a working length that supports mid-depth drilling tasks. The construction ensures resistance to wear under typical operating conditions and maintains drilling accuracy over multiple uses. Its shank and flute design provide reliable chip evacuation and steady engagement with the workpiece, helping reduce wobble and improving hole roundness.

How to use

Secure the drill bit in a compatible chuck, ensuring it is held straight and tightened. Select an appropriate drill speed and feed rate for the material being drilled: lower speeds for harder metals, higher speeds for wood and soft materials. If drilling metal, use cutting fluid or lubricant to reduce heat and extend bit life. Apply steady pressure without forcing the bit; allow the drill to cut at its designed rate. After completing the hole, clear chips from the flutes before removing the bit.

Recommendations

Use personal protective equipment such as safety glasses and gloves. Match the drill speed and lubrication to the material to maximize bit life and hole quality. Inspect the bit for wear or damage before use and replace if the cutting edge is chipped or excessively dull.
