Tin Coated Jobber Drills - JLDTF
Jobbers Length Drills are now available with wear-resistant Titanium Nitride coating. This superhard coating can increase tool life up to 500% over uncoated drills by reducing galling and built-up edge formation. The coating aids chip removal, and remains on rake faces and wear lands for many resharpenings.
