The Evolution Series Long Hole Boring Bit 8mm has been specifically designed to drill accurate holes in the end grain of wood mounted on the woodturning lathe.

The parabolic flute design of this bit clears the chips quickly and prevents chip burn. Like most long hole augers it is necessary to withdraw the 8mm boring bit frequently during the drilling out process, thisĀ  will help to clear the waste and reduce the risk of overheating.

The Evolution Series Long Hole Boring Bit 8mm is 880 mm in length with a 6.5 mm shank and a bit diameter of 8mm at the tip tapering to 7.9mm for clearance.

Made in Austria from top quality HSS-M2 steel. A worthwhile accessory is the “twist-lock” handle (178 x 30mm) which is available separately. Made in Axminster from steel with a comfortable rubber grip, this handle will allow accurate hole depth and prevent accidental contact of the bit with your counterbore drive.
