hollow drill bit

 

cnc cemented carbide hollow drill bit

 

1:Name: Woodworking Drill Bits - longlifeThrough-Hole("V" Point)Boring Bits

 

2. Advantages for longlife through hole V-point drill :

(1). Better for machine tool's high rotary speed and high speed and low speed cutting.

(2). Second main cutting edge adopting Achimedean spiral principle will make the edge much more sharper and with better impact resistance.

(3). Adopting two angles' clearence angle and the design of many main cutting edges to disperse cutting force,will effectively avoid edge crack and inactiviation, and prelong operating life three times longer than usual unicuspid

 

3.Suggested Parameters :

Used for CNC and drill rig machining

Speed: 4500-8000 (r/min)

Feeding speed: 2-8 (m/min)

Maximum drilling depth: length 57, deep 20mm; length 70, deep 33mm.
