High-performance core drill bits with 55-mm cutting depth, AlCrN-multilayer coating and 8% cobalt alloy for high service life and versatile use with almost all materials such as in conventional steels, cast iron, titanium, stainless steels, heat-resistant and high-strength steels up to 1400 N/mm² in strength. Also suitable for non-ferrous metals, such as aluminium, aluminium alloys, magnesium alloys, brass, bronze and plastics.

Outstanding performance compared to similar uncoated core drill bits


  • Significantly higher service life

  • Up to 60% greater cutting speed

  • Considerably faster drilling progress


AlCrN multilayer wear-protection coating and 8% cobalt alloy


  • Extremely high temperature resistance of up to 1050°C

  • Very high coating hardness of 3000 HV

  • Multilayer construction for optimum chip removal and improved cutting properties (prevents material wear)


For process reliability in almost all materials



Exact guidance, no slippage


Problem-free drilling on curved surfaces and pipes



No predrilling required, no formation of burrs


Eliminates need for pre- and post-machining

Notice
  • Unlike the twist drill, the core drill bit does not machine the entire bore diameter, but rather only a thin material ring. The drill core is ejected by an ejector pin using spring tension; this is not included in the scope of delivery. The drilling times of core drill bits are therefore up to ten times shorter than those of twist drills.

  • Sufficient continuous cooling during the entire drilling process considerably increases the service life of the core drill. Do not use in a dry state.

  • See the overview tables for core drill bits/material assignments as well as cutting values

  • Wear appropriate protective equipment when using the sanding tip, such as Eye protection, hearing protection, protective gloves

  • Set aside loose clothing or jewellery that could get caught in moving parts

  • The core drill bits must not be used manually

  • Before use, please ensure that the tool rotates properly and that the clamping function on the tool drive works correctly

Application area
  • With Weldon shank ∅ 19 mm for use on mobile magnetic drills or stationary drills for creating large holes up to 50 mm in diameter and a cutting depth of max. 55 mm

  • Fein drills with QuickIn mount can be used with an adapter

  • Application on stationary drills with Morse taper is possible using the appropriate mount holder
Instructions
  • Insert the ejector pin into the core drill bit

  • Push the core drill bit into the mount holder of the drill unit and tighten the hexagon socket screws

  • The core drill bit is automatically locked into place when using quick-action mounts

  • Make sure the core drill bit is sitting cleanly in the mount

  • Putting the drill under lateral load during use may cause the tool to break

  • Fix the drill unit into the right position for drilling — make sure the drill unit has a stable footing

  • If necessary, secure the drill unit before drilling using a safety strap, especially for use on vertical surfaces and overhead work

  • Pay attention to the speed table and use coolant

  • Drill carefully (without centre punching and pre-drilling), pay attention to an even feed and even rotation speed throughout the entire drilling process

  • Remove chips and drill core after each drilling operation

  • Caution: Risk of injury, chips and drill core may be very hot and sharp
