Drill bit set Proline Universal CTi Proline 3x75mm Urbis 5767035

Proline Universal CTi Proline 3x75mm drill bits (MPN 5767035, EAN 5903755767035) are universal drill bits with a chrome-vanadium steel shank and special CTi alloy cutting plates made from cobalt and titanium‑tungsten steel. The set contains three 75 mm bits designed to provide high hardness, wear resistance and temperature resistance for a wide range of drilling tasks in common building and workshop materials.

Advantages

The CTi cutting plate composition delivers improved hardness and extended life compared with standard HSS bits, while the chrome-vanadium shank offers rigidity and corrosion resistance. The three-piece 3 x 75 mm set ensures consistent hole size and quick replacement between tasks. These bits are compatible with most standard drills and are balanced for stable drilling performance.

Suitable for

• Drilling glass and porcelain
• Drilling ceramic tiles and fiberglass
• Drilling concrete, marble and granite
• Drilling cast iron and hardened steel
• Drilling wood, plastic and laminates

How to use

Fit the 3 x 75 mm Proline bit into the drill chuck and secure it tightly. Start drilling at low speed to mark the surface, then increase speed as appropriate for the material. Use steady pressure and avoid overheating by pausing or using cooling/lubrication when drilling hard materials such as metal, stone or concrete. Replace bits when wear affects drilling accuracy or cutting performance.

Usage recommendations

For best results, match drill speed and feed pressure to the material: lower speeds for metals and hard stone, higher speeds for wood and plastics. Use water or suitable coolant when drilling ceramics, concrete or stone to reduce heat and prolong bit life. Inspect bits regularly for chipping on the CTi cutting plate and replace if visibly worn.
