Solid Carbide Gundrills
Solid carbide gundrills by Botek offer superior penetration rates than carbide twist drills or conventional gundrills in dedicated deep hole drilling machines or CNC lathes and mills.
The solid carbide range of drills are available from Ø0.7mm to Ø12.0mm for drilling holes up to 100 x drill Ø in a single pass.
The specialised geometry of the Type 113 HP drills allows 800% increases in feed rates and is ideally suited to cutting long chipping materials and are also suitable for drilling with cutting oil, MQL and high quality emulsion.
Lite-Cut geometry reduces the cutting force and gives reliable chip breaking in difficult to machine materials. The result is improved chip removal, faster penetration and superior drilling quality.
A high level of penetration from Solid Carbide Gundrills allow for a clear, cleaner finish.
