Specification
Brand : wolfcraft
BulletPoint1 : tungsten carbide coated annular bit insert for drilling holes in brick walls and stone
BulletPoint2 : available in various diameters, 55 mm cutting depth - ideal for building projects or renovations
BulletPoint3 : can only be used with the separately available receptacle plate (art. no. 3472000/3466000) and centring drill bit with hexagon shank (art. no. 3471000), TÜV-tested quality for peace of mind
BulletPoint4 : The biggest advantage of HSS annular slugger drill cutter bits is its ability to re-sharpen and burr-free holes and smooth holes, resulting in less scrap and wastage of material,has higher accuracy and multiple cutting edges for ply-cutting and lower friction to reach better performance of endurance and removal of chips.
BulletPoint5 : Includes 1 annular cutter and 1 pilot pin(6.34*103mm) with plastic case.

Application

The cutter is used for drilling through steel. They produce accurate burr-free holes to close tolerances without pre-drilling or step drilling. They can drill a much larger hole and requires less force and time than a standard twist drill bit.

The annular Cutter offers superior holemaking capabilities. It cut faster, last longer, produces a better hole finish, a true round hole with very tight tolerances, can be re-sharpened and drills holes with less power and torque.

Requirement to cutting rotate speed of annular cutter are also different for different diameters,and reasonable cutting rotate speed will prolong service life of annular cutter directly,So we recommend:1.The cutting speed:VC=20-25m/min 2.The reasonable rotate feed amount shall be fn=0.08-0.13mm/r 3.The reasonable feed rate shall be vf=36-60mm/min 

Notes

What Causes Dull or Broken Cutters?

The primary cause of broken or prematurely dull cutters is a feed rate that is too slow. Slow feed rates will reduce the life of your cutter. Using a firm, steady feed pressure throughout the cut will maximize performance and extend tool life.
