Drill Bits Proline Universal type CTi Proline Urbis 4x80mm is a universal 4 mm diameter, 80 mm length drill bit intended for general-purpose drilling. The shank is made of chrome-vanadium steel and the cutting plate is manufactured from specialized steels containing cobalt and titanium tungsten, which increase hardness, wear resistance and temperature tolerance. The bit is suitable for drilling a wide range of materials including glass, porcelain, ceramics, concrete, marble, cast iron, wood, plastic, fiberglass, granite and laminate.

Advantages

The chrome-vanadium steel shank provides secure clamping and durability, while the cobalt and titanium-tungsten cutting plate delivers improved hardness and resistance to wear and heat. The universal design enables drilling into a variety of materials with a single bit, reducing the need for multiple specialized drills. With a 4×80 mm size the bit is suitable for precise small-hole work and common workshop or DIY tasks.

How to use

Secure the 4×80 mm drill bit in a compatible drill chuck. Select appropriate drill speed and apply moderate, steady pressure according to the material: lower speeds for hard materials such as tile, glass or metal, and higher speeds for wood or plastic. Use cutting fluid when drilling metal to reduce heat and wear. For brittle materials (glass, porcelain, ceramic), start with light pressure and consider backing material or masking to reduce chipping.

Usage recommendations

Inspect the bit for damage before use and wear appropriate eye protection. Replace the bit if the cutting edge becomes dull or damaged to maintain drilling accuracy and safety.
