About this item
- Drill bit set dimensions: Core drill bit - Ø 75 mm, working length 60 mm, total length 162 mm, (8 x 110 mm center drills) x2, SDS plus adapter 110 mm (M22 thread), 1 fastening screw, 1 combination wrench length 140 mm.
- High-quality alloy steel: The drill body is made of high-quality carbon steel, the drill tip is supported by YG8C cemented carbide, and it features replaceable drill bits. Cutting center drills keep the drill centered and prevent slippage. It runs smoothly and features two chip removal holes to remove dust generated during drilling. The cutting speed is high, and the hole diameter is uniform and clean.
- Wide Application: Used for countersunk holes in concrete, masonry, drywall, brick, sandstone, suitable for drilling holes for the installation of air conditioners, water heaters, range hoods, exhaust pipes, etc.
- Packaging and Instructions: Each hollow block and adapter extension shaft are individually packaged in a plastic box for easy storage and coated with oil to protect against rust. Touching the wall reinforcement is strictly prohibited during drilling, as otherwise the drill bits will pop out. The saw must be guided straight and precisely. A long service life can only be achieved with appropriate cooling using drilling spray or drilling fluid.
- Compatibility: This drill bit fits all impact drills with SDS-plus chuck.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
