Large dia holes are a sweat no more

A new line of high productivity head changeable drills for large diameter hole-making.

Producing large-diameter holes can be a big headache for many shops that are aiming to be cost effective and competitive in today's global market.

TaeguTec has introduced the SpadeRush, a new line of high productivity head changeable drills for large diameter hole-making. Its optimised cutting edge and unique rigid clamping system generates outstanding performance while reducing cycle times in large diameter hole making.

Available as a standard drill in 3xD and 5xD for a diameter range of 26 to 41 mm, the SpadeRush's unique clamping technology enables customers to quickly change drill heads without removing the clamping screw from the holder - an important feature that greatly reduces tool setting times and also machining downtime.

Furthermore, the asymmetrical base design of TaeguTec's SpadeRush means error proof insert mounting, high tolerance, improved tool accuracy as well as repeatability, and an excellent surface finish.

Its self-centered design eliminates the pre-centering function that many shops have to put up with when performing large diameter hole making applications.

The SpadeRush's through-coolant hole feature permits coolant to be applied directly to and in the hole-making area which also prevents the tool and holder from premature wear and damage. The post-treatment of the SpadeRush's flute design improves chip evacuation, reduces power consumption and strengthens vibration dampening, which strengthens the tools durability.

Several tests were performed while creating TaeguTec's new line, and invariably, SpadeRush outperformed the competition. In one case, for example, of alloy steel drilling, SpadeRush outperformed a popular competitor's similar tool by increasing tool life by 30 percent at exactly the same cutting conditions.
