Heavy drilling performance with Makita
- Four robust carbide cutting edges: The solid four-cutter head allows you to bore smoothly through reinforced concrete without jamming on internal rebar.
- Fast and clean dust extraction: Optimized spiral flutes channel debris away rapidly, helping you maintain fast drilling speeds and reducing core wear.
- Accurate centering on start: The integrated centering tip keeps your bit firmly in place so you achieve exact, clean entry points without slipping.
Tackle heavy penetrations for pipes, cables, and drainage ducts with the Makita P-78140 SDS-Max hammer drill bit. Its solid carbide head with 4 cutting edges powers smoothly through reinforced concrete, masonry, and natural stone while minimizing snagging when hitting rebar. The integrated centering tip prevents bit walking on startup, and the wide spiral flutes remove dust rapidly to maintain fast drilling speeds and reduce wear. With a 38 mm diameter and a 450 mm working length, this bit lets you complete deep drilling jobs in a single pass on any SDS-Max rotary hammer.
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.
