Ultra Cut Super Premium - Type 490-G

Special Hi-Molybdenum tool steel, gold surface treated for maximum lubricity. 135° split point for fast penetration and accurate starting without a center punch. Extra rugged uncleared construction gives superior performance and less breakage.

Heavy Duty 135° Split Point - Type 490

The twin end drill has wide applications in drilling any thin sheet metal or wood. Automotive body shops will find twin end drills especially productive.

Remove broken screws, bolts, threaded parts and pipe. Drill a hole in broken part, insert extractor and turn to the left. Broken piece is extracted without damage to threads.

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.

Sets

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 spotwelds with the added advantage of longer reach to drill the less accessible spotwelds.

There are many spotweld 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 spotweld drilling available to all body shops.
