Jobber-Length Drill Bit
Westward 5TVK5 is a 12-inch aircraft drill bit made from high-speed steel with a black oxide finish. It features a 1/8-inch diameter and a 135-degree split point for accurate starting in metal. The jobber length provides extended reach for deep-hole drilling tasks.
Suits Deep-Hole Metal Drilling
This bit suits machinists and maintenance technicians drilling deep holes in steel or alloy where a standard-length bit cannot reach. The split point reduces walking on hard surfaces. It does not suit users who need a coolant-through design for high-volume production or bits for wood, masonry, or large-diameter holes.
12-Inch Overall Length
The 12-inch overall length is the critical specification that determines if this bit reaches the required depth. The 1/8-inch diameter and .1250 decimal equivalent define the hole size. The 135-degree point angle and high-speed steel material suit general-purpose metal cutting.

Questions about this item
What drill-bit point angle does the 1/8 in bit use?
The bit has a 135-degree split point that reduces walking and starts holes cleanly.
What shank size fits a standard drill chuck for this 12 in bit?
The 1/8 in shank matches common three-jaw chucks up to 3/8 in capacity.
How do you install the bit so the split point engages properly?
Insert the shank fully, tighten the chuck evenly on all three jaws, and avoid over-tightening which can mask the split-point benefit.
