Forstner Bit Woodworking Drill Bit Set Boring Hole Saw Cutter Carbide Tip TCT Hex/Round Shank
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. Should be use with power drilling machine, here is not included.
Please Note:
1.When drilling holes, forstner drill bit is made only in the clockwise direction, not reversible, and the speeds from low to high is a gradual process.
2.Please grind the tool nose and tips to avoid ageing and damage when breaking; or it will cause a steep decrease in accuracy and quality for drilling holes after tips break.
