4 Flute Hole Hog ™ Super Premium Drills
Special Hi-Molybdenum tool steel, gold surface treated body and clearance for maximum lubricity. Close tolerance construction. This tool is designed for enlarging existing holes exclusively. The 4 flute design eliminates the catching and hogging-in experienced with standard S & D drills when breaking through thinner materials such as truck frames. These core drills may replace tapered reamers in many applications. 3 Flats on the shank.

Bolt Remover Sets
A unique combination of left hand spiral drills and bolt/screw extractors. Both BR sets provide these benefits: (Also see BR-8SQ below)
Fast and easy stud removal.
Left hand spiral drills often eliminate the need
for bolt and screw extractors.
Drill may loosen bolt stud with counter clockwise
rotation.
135° split point drill will cut harder metals
than a 118° point drill. Most broken studs are work
hardened during the breaking process.

Studout ™ Super Premium Forged Hi-Carbon Steel, Gold finish
The square shape of these extractors gives the tools the ability to remove broken bolts, screws and pipes with minimum deformation of the broken part. The forged construction imparts an extra degree of toughness, which reduces extractor breakage. To remove the broken threaded part: Drill a hole in the end of the broken part (left hand spiral heavy duty drills are recommended for this drilling operation), insert extractor and turn counter clockwise using a wrench on the exposed end of the extractor. The broken part should unscrew without damage to the threads. These forged extractors will not chew up or expand the object being removed.

Type 492-D
This rugged high performance drill is designed to effectively cut auto body panel spot welds. The high red hardness of cobalt steel permits speeds 30% greater than H.S.S. drills. Cobalt steel is substantially more abrasion resistant, resulting in very long wearing cutting edges. The spur point on the Type 492-D is designed to cut through the weld on one panel while leaving the second panel free of holes. The modified point of the Type 493-D drill is chip resistant with slightly greater penetration into the second panel.

* These twin end drills will cut twice as many spot welds with the added advantage of longer reach to drill the less accessible spot welds.
There are many spot weld drilling systems in use. Some have a significant amount of adjustment for the length of the drill. If you have a system that will not operate using one of the lengths specified, special lengths can be made to accommodate your needs. Call for price. The three sizes without flats are for use in standard air powered drill motors. This makes freehand spot weld drilling available to all body shops.
