Westward 5UDD9 1/4" HSS Black/Gold 135 Deg Jobber Drill Bit

1/4" HSS Jobber Drill Bit

This Westward 5UDD9 drill bit is a high-speed steel cutting tool sized at 1/4 inch with a decimal equivalent of .2500. It features a 135-degree split-point tip in a black and gold finish. The jobber-length design suits general-purpose drilling tasks in metal, wood, or plastic for professional tradespeople and maintenance crews.

Suits General Purpose Drilling Not Coolant Through

This bit suits users needing a durable fractional-inch drill for portable or stationary machines where split-point accuracy helps reduce walking. It is not for buyers who require coolant-through capability for deep-hole chip evacuation or high-volume production drilling. Operators needing specialised coatings for exotic alloys should look at something else.

135 Degree Split Point Angle

The 135-degree split-point geometry is the specification that determines suitability for harder materials and self-centering starts without a centre punch. This angle reduces thrust requirements compared to standard points. The high-speed steel substrate and black and gold surface treatment support the bit's performance in ferrous and non-ferrous applications.
