excavation tool system and BHA04 holder, fitted
A satisfied user: Robert Geitner of Max Bögl
Betek, one of the world’s leading manufacturers of tools tipped with tungsten carbide, is unveiling a new generation of quick-change bar / holder systems at the BAUMA show: the BA47 tool systems are used on drilling machines with a pipe wall thickness of 40mm and are excellently suited to all sub-surfaces and rock types.
New on the BA47 type quick-change bars – supported by typically innovative Betek product design - are round elements of tungsten carbide for optimum penetration into the rock. An additional tungsten carbide pin helps to produce increased protection against wear. The layout of the pins has also been redesigned to meet users’ needs, while the BHA04 holder system has been reworked as well, incorporating particularly effective lateral anti-wear protection. Using special locking pins, the quick-change bars can be easily changed with minimal effort on the construction site itself. The entire system increases the tools’ efficiency, thus producing significant benefits for the user.
Even in difficult drilling conditions, the tools’ tungsten carbide elements ensure that they last an extremely long time.
The system has already been able to prove its worth in practical use in all sorts of excavation applications, including in numerous major pile foundation projects in city centres such as Stuttgart and Munich. Here are the views of one user, who achieved substantial savings using the new Betek system:
Mr Geitner, you work for Max Bögl in the company’s machine engineering department and look after construction sites. Which of Betek’s tools do you use for the machines?
In the main it’s tools for road building and civil engineering work, so for areas of use with high levels of wear. We mainly drill, after all, into concrete and rock. And our experience in this regard with Betek has been very good, especially in terms of drilling accessories.
I understand that you collaborated with Betek on the development of some quick-change bars. What was the result of your joint development work?
An A1 tool – there’s no other way of putting it! Its cutting performance and wear characteristics are much better than anything else on the market.
What do you base that verdict on?
On the fuel consumption, for example. The drills, after all, are powered by 600 to 700 PS diesel motors. If a tool cuts well, you get an enormous saving in fuel. It can be as much as 10 to 15 litres – an hour!
Have you ever done any comparison tests?
Yes, on a construction site in Stuttgart. Using Betek quick-change bars we achieved cutting performance that was 20% better and drilling performance that was three times greater.
From your perspective, what sets Betek apart?
Well, I look after a lot of machines and construction sites. Naturally some problems crop up. In such cases Betek is always responsive. If needs be, an expert comes out to the site, someone who knows a fair bit about the work we do. Such professional support is certainly unique in the market and Betek practically always manage to find a solution. Then there’s also the consistent quality of the tools. Its consistency is noticeable and unusual. Indeed, I’m well placed to make such comparisons, as our company also uses other manufacturers’ tools. In Betek’s case everything always fits perfectly!
