Powerful drilling with Makita
- Accurate and smooth holes: The solid four-cutter carbide tip lets you drill precise holes without jamming on reinforcing steel.
- Fast drilling dust removal: High-volume flute spirals clear debris rapidly so you maintain high drilling speed and reduced heat.
- Maximum impact energy transfer: The SDS-MAX shank locks directly into your hammer to deliver full power straight to the tip.
Power through reinforced concrete, masonry, and natural stone with the Makita P-77811 hammer drill bit. Its solid four-cutter carbide tip prevents jamming when striking rebar and creates clean, accurately sized 20 mm holes essential for secure anchoring and service penetrations. The high-volume flutes clear dust rapidly across the 200 mm working length, reducing friction and maintaining fast drilling progress. Fitted with an sds-max shank, it transfers maximum impact energy directly from your rotary hammer to the workpiece, giving you complete control during heavy-duty drilling tasks.
Product description
TCT drill bit 20 x 200 / 320 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 320 mm, a working length of 200 mm and a diameter of 20 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.
