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¨Dnearly midway between that of lead and gold. It is comparable with corundum (©¶-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.

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.
