VIKING DRILL & TOOL: Type 240-UB Drill Bit

 

B.I.R.S. Machine & Supply distributor of Viking Drill & Tool Type 240-UB .. 135 split point.

 

 

 

Viking Drill & Tool Type 240-UB Ultra Bor Super Premium drill bits are manufactured to NAS 907B specification from premium Hi-Molybdenum Steel, which is much tougher than cobalt steel. Type 240-UB Ultra Bor are jobber length drills. 

 

Ultra Bor will substantially outperform cobalt drills in work hardening stainless steel and other tough applications. Ultra Bor are Nitro-Carburized.

 

 

 

 

 

 

 

Ultra Bor Super Premium Drills have a thin web that will penetrate work hardening stainless fast enough to continually cut beneath the chip which is hardening from deformation. The cobalt with its thick web cannot be fed at a fast enough rate to cut beneath the area which is hardening.

WHY CHOOSE ULTRA BOR?

 

Substantially longer cutting life

The nitro-carburized flute has an increased Rockwell hardness. 

 

Cuts harder materials

The flatter point takes a smaller chip. More torgue 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.

 

Holds tigher hole sizes

The split point design is self centering. This limits the normal oversize drilling

characteristics.

 

Outstanding quality appearance

The rich amber gold color sets it apart fromm commodity cutting tools.

 

Runs cooler, uses less torqe

135* point takes a smaller chip resulting in less heat. Friction is reduced by amber gold.

 

Stops chuck slippage

Flats on drill shanks allow easy positive chuck grip.
