15-100mm 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 Young's modulus of approximately 530–700 GPa (77,000 to 102,000 psi), 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 holes cleanly in end
grain and thin stock, great for boring concealed hinges and door locks.
DESIGN WITH CURVE
In a design with curves, the head is good at removing the debris and working efficiently.
Features:
Please Note:
1. When
drilling holes, the Forstner drill bit is made only in the clockwise
direction, not reversible, and the speeds from low to high are a gradual
process.
2. Please grind the tool nose and tips to avoid aging and
damage when breaking, or it will cause a steep decrease in accuracy and
quality for drilling holes after the tips break.
