16-25mm Extral Long 130mm Forstner Bit Woodworking Drill Bit Set Boring Hole Saw Cutter Tungtens Carbide Tip TCT With Spiral Groove 1/4" Hex Shank

YG8 Tungsten Carbide Tip
YG8 Tungsten Carbide also known as ISO K30 Tungsten Carbide.
Which density is about 14.5-14.9 g/cm3. The hardness of it is about 89HRA.The bending strength of it is 1500σbb/MPa and the the impact toughness is about 2.5J/cm2.
The tungsten carbide tipped drill bit head is harder, tougher, and more resistant to extreme loads, which is specially designed to cut through hole cleanly in end grain and thin stock, great for boring concealed hinges and door locks.

Spiral Slot Design
Spiral slot design with fast drilling debris remove, hex shank allows drill bit to be quick changed & held tightly and stably in power drill. Efficiently debris removing is necessary when drilling deep hole.

Head 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.
