Rosnek 15-100mm Forstner Drill Bit Woodworking Drill Bit Set Saw Cutter Carbide Tip TCT Hex/Round Shank

Descriptionz: * TUNGSTEN CARBIDE TIP(TCT) Tungsten carbide is approximately twice as stiff as steel with a Young s modulus of approximately 530-700 GPa (77 000 to 102 000 ksi) and is double the density of steel—nearly midway between that of lead and gold. It is comparable with corundum (α-Al2O3) in hardness.Tungsten Carbide tip is specially designed to cut through hole cleanly in end grain and thin stock great for boring concealed hinges and door locks. * DESIGN WITH CURVE In design with curve the head is good at removing the debris and working efficiently. Features： 1. Forstner Bit drill clean holes in soft and hard wood. 2. Two spurs and centering point to give the perfect solution to repeated clean and accurate hole cutting time after time. 3. The sharp center spur accurately locates the center of your hole. 4. Use to drill precise flat bottom holes with no chipping in any thickness of soft wood. 5. For drilling holes in any direction and making arched openings. For drilling partially overlapped flat bottom holes for easy mortising. 6.
