Spot weld drill bits
Great cut Spot Weld Drill Bits - are made of top quality.
or solid carbide
are made of top quality, This high-speed steel is mixed with a special cobalt alloy (EMO5-CO5), resulting in drills that can be expected to last twice as long as standard high-speed steel bits.
Measuring 1 1/4" long x 5/16" diameter, they can be used in any drill which runs between 700 to 1800 rpm. Of course, as with any cutting tool, use of a cutting oil will greatly increase the life of the tool. Once you use an Great cut Spot Weld Drill, you'll never go back to hole-saw-type cutters again.
A) 90151 -10 - This is the HSSE bit which contains the special cobalt alloy - lasts twice as long as HSS bits. This bit features a 10mm diameter cutting face.
B) 90151 – Same as above, but with an 8mm diameter cutting surface.
C) 90151-TIN - You know these bits are different the minute you look at them. We took our HSSE cobalt alloy bit and coated it with space-age Titanium, which is what gives the bit its gold color. The durable, titanium coating on these bits makes them last three times longer than our 90151 HSSE cobalt bit.
D) 90151-TICN - This is the top of the line bit - Titanium Coated and Carbon Nitrited. This exceptional coating is extremely hard while offering a very low coefficient of friction, so it runs cool. The bit’s purple color comes from the carbon nitriting process, which makes this bit last four to five times longer than the standard HSS bit.
E) 90151-3 – This is machining use solid carbide material, TiALN coated. This spot weld drill bit features a special, three-fluted design and combines all of the benefits of TiN, TiAN, and TiCN coatings. Watch it cut through these unusually hard steels while other drill bits just dull. Not recommended for use in a drill, but are designed specifically for specialized spot weld cutting tools
