Description

NDT-CT-29P

This 29 pc. drill bit set is very proudly made in the USA.  This is Norseman Drill & Tools HSS Heavy-Duty CN-TECH Drill Bit Set.  These are ‘Jobber Length’ straight shank with three flats drill bits in a really nice round red ultradex thermos type case that makes finding and returning each bit really easy.  This set is 1/16″ to 1/2″ by 64th’s.

Why Choose CN-TECH?

  • Substantially longer cutting life – Superior to Cobalt bits, ultra hard, super premium drill bits that are designed not to snap and shear during hard drilling, even at awkward angles.

  • Cuts harder materials – The flatter point takes a smaller chip. More torque is directed to a smaller area. This allows drilling into materials with hardness of over 30 on the Rockwell “C” scale.

  • Stops drill walking – The split point design gives accurate starting without the use of a center punch.

  • The Nitride process – Diffuses nitrogen into the surface to create a case hardening resulting in superior tool life and exceptional corrosion resistance. Recommended for work hardening grades of stainless steel and other hard metal drilling application.

  • Cryogenic treatment – Creates a more uniform “grain” structure by transforming retained austenite into martensite.

  • Runs cooler, uses less torque – 135° point takes a smaller chip resulting in less heat. Friction is reduced by surface treatment.
