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

Product information

Würth Catalogue

Datasheets(X)

Certificates/ Documents

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

x 1 pcs

The packaging unit defines the number of articles in one packaging. In the catalog segment you can choose from different packaging units if a pop-up menu is displayed.

Just leave the field empty if you don't know the packaging unit when directly entering the article number in the shopping basket or when importing with Easy-/VarioScan. The packaging unit will be determined automatically.

The article number is made up of the following: VVVVAAABBB
VVVV = 4 digits for prefix number (please note that the first digit is currently always 0)
AAA = 3 digits for dimension part 1
BBB = 3 digits for dimension part 2

Example article number structures:
Example 1: Screw with dimensions of 4x10 mm:
VVVVAAABBB
00574 10 (2 spaces between the 4 and the 10)

Example 2: Screw with dimensions of 10x20 mm:
VVVVAAABBB
005710 20 (1 space between the 10 and the 20)

Example 3: Flat washer with an internal diameter of 6 mm:
VVVVAAABBB
04076

Price per packaging unit (PU):
The displayed price is always in line with the displayed packaging, if the PU is 250 the price for 250 units, if the PU is 300 the price for 300 units.

Price with price key representation (PSL):
The price always applies to a quantity ruled through the price key:
Price for 1 unit
Price for 100 units
Price for 1000 units

The quantity shows the number of pieces or units of measure contained in the order or delivery for the respective article.

In contrast to sales packaging and secondary packaging, the disposal costs for chemical-technical products are shown separately. The breakdown of the individual costs can be found on the relevant products and also in the shopping cart, as well as in our General Terms and Conditions (GTC).
