Drill bit KWB 206533, 3.3 mm, right-hand rotation, single-piece blister pack

KWB 206533 is a single-piece 3.3 mm drill bit designed for right-hand rotation drilling. The solid cylindrical shank and precision-ground flute geometry conform to DIN 338 and the cross-ground tip follows DIN 1412 C. The bit has a 135° tip angle and a type N, self-colouring finish. It is manufactured for industrial quality performance and supplied in a single blister pack for individual use.

Advantages

The drill bit offers a precision-ground cutting edge for accurate hole placement and reduced walking on the workpiece. Its 135° tip angle and cross-ground geometry provide reliable self-centering and efficient chip evacuation. The cylindrical shank ensures compatibility with standard drill chucks, while the industrial-quality construction suits intermittent professional and DIY use.

Suitable for

• Drilling steel and alloyed steel
• Drilling cast steel and die-castings
• Working with sintered steel
• Drilling non-ferrous metals (e.g., aluminium, brass)
• Drilling hard plastics

How to use

Secure the drill bit in the drill chuck ensuring concentric clamping on the cylindrical shank. Select a drill speed appropriate to the work material and apply steady axial pressure. For metal drilling, use cutting fluid to reduce heat and extend tool life; for plastics, use lower speed and minimal feed to avoid melting. Retract periodically to clear chips when drilling deep holes.

Использование

The drill bit is intended for conventional drill setups and intermittent professional or DIY tasks where a precise 3.3 mm hole is required. Avoid excessive side loads and use appropriate speeds and lubrication for the material being drilled.
