• [SPECIAL DESIGN] 3-Cutter forstner drill bits have faster cutting speed and longer service life compared with 2-cutter ones. Using these sharp drill bits, you can drill accurate, smooth, neat holes without burrs, even in end-grain and through knots. Arc curve design head contributes to removing sawdust faster, making your work more efficient.
• [MATERIAL] The cutting edge is made of 3 pieces of K35 monolithic tungsten carbide, hardness 91HRA, bending strength >2200N/cm2, resharpenable for a longer service life. It has the advantages of high hardness, wear resistance, good toughness, heat resistance and corrosion resistance. The shank is made of steel 45#.
• [SPECIFICATIONS] Drilling dia.: 40mm; shank dia.: 9mm; drilling depth: 60mm; total length: 90mm.
• [NOTE] 1. Sharp parts contained, please keep away from children and pets. 2. Can NOT be used for metal processing, or the will drill bits get damaged quickly. 3. Material must be fixed during cutting, and the drill bit should be perpendicular to the material. 4. Set slow drilling speed till the drill bit is completely located, then gradually accelerate speed. 5. Water should be injected when processing hardwood, in order to improve drilling accuracy and quality.

• [SIZE]: Specification: M8*60mm; Total Length: 85mm (3.35\"); Thread Diameter: 8mm (0.31\"); Bolt Length: 60mm (2.36\"); Lifting Ring Diameter: 7mm (0.28\"); Hole Size: 12mm (0.47\"); Drilling depth: 45mm (1.77\"); Quantity: 2
• [MATERIAL]: Made of high quality 304 stainless steel, they have good corrosion resistance, rust resistance and high hardness, which provides a longer service life, can be used indoor and outdoor, even in humid environment.
• [APPLICATION]: Expansion eyebolts are suitable for fastening items to concrete, bricks and walls, they are widely used for hanging heavy objects, fixing wire ropes, home decoration, engineering installation, etc.
• [HOW TO USE]: 1. Select a bit with the same diameter as the expansion screw casing, install it on the electric drill and dirll a proper hole; 2. Insert the expansion bolt into the hole, tighten the nut with a wrench and then tighten the lifting ring.
• [PRECAUTIONS]: 1. When using percussion drills to punch holes, they must be punched vertically, and the hole diameter cannot be too large, otherwise the tightness will be affected. 2. When it is installed upside down on the roof, it must be installed on a solid material. It is not suitable to install overweight objects, nor can it install machines with large vibrations, because there is a risk of falling due to vibration and overweight.
