Cost-effective and process-secure drilling system

Posted on 14 Jun 2020 and read 931 times
Cost-effective and process-secure drilling systemThe Komet KUB Centron is a tried-and-tested drilling tool that has been available for many years, providing cost-effective and process-secure drilling in hole depths from 4xD to 9xD.

Previously, they were only available to order as semi-standard tools, but in a move to make them more widely available, the drills are now in-line with the majority of tools from Ceratizit UK and Ireland (www.ceratizit.com) with ex-stock delivery now standard across the range.

Suitable for rotating and stationary and vertical or horizontal applications the KUB Centron covers diameters ranging from 20 to 81mm and up to 9xD, making it ideal for drilling transverse holes in housings or holes in cylinder blocks and forged parts.

The drill’s modular design enhances its cost-effectiveness, with the tool comprising a holder, drill head, indexable inserts and centring drill tip. The drill head is located on the holder by means of a custom-fit centring pin, the head is held in place by two tapered screws acting in the torque direction, which pull it onto the drive dogs.

This combination ensures a precise and stable connection, completing the assembly are adjustable carbide guide pads for added stability when drilling and exiting the hole, thereby counteracting deflection.

For drills up to 65mm diameter just two indexable inserts are used, above that diameter this increases to four, supported in pairs in cartridges.

Key to the success of KUB Centron is the eponymous centring tip, which is available in solid carbide or HSS – with a TiAlN or TiN coating. This tip guides the tool exactly in the drill axis ensuring dimensional stability, straightness and maximum process security, even with a maximum hole depth of 9xD.

The optimised run-out properties of the complete system make a long service life possible for the drill point and indexable inserts.

Tony Pennington, Ceratizit UK & Ireland managing director, said: “While the Kub Centron system has been available for some time and has proved its effectiveness across many applications, the strength of the Ceratizit Group can now make that drilling efficiency more widely available. By ensuring that tools, such as Kub Centron are available ex-stock for next day, before noon delivery our customers can rely on Ceratizit.”
