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.

Questions about this item
How much heat builds up when the 135-degree split point runs continuously in steel?
The 135-degree split point reduces thrust and friction, so the bit runs cooler during extended drilling in metal.
What shank style does the 1/4-inch bit need to fit my drill?
The jobber-length bit has a straight round shank that fits standard three-jaw chucks.
Will the .2500-inch diameter match my existing 1/4-inch taps and clearance holes?
Yes, the .2500 decimal equivalent is the standard 1/4-inch size used for matching taps and bolts.
