Product description

TCT drill bit 38 x 450 / 570 mm, SDS-MAX

High-quality and durable SDS-MAX Zentro drill bit with a tip with 4 cutting edges for drilling in concrete and natural stone. Excellent grit removal thanks to shortened spiral grooves. This bit has an overall length of 570 mm, a working length of 450 mm and a diameter of 38 mm.

The Zentro drill bit with SDS-MAX connection is specially made for drilling in concrete and stone. The sharp and centred tips allow precise holes to be made. Compact, high-volume spiral grooves remove dust very efficiently during drilling. When drilling in natural stone, it is recommended to use cutting oil or equivalent to cool the blade. This significantly extends the life of the blade. Natural stone is a very hard material and if deep holes are drilled continuously, the blade gets hot and may eventually break.
