We are leaders in the market for providing best range of Bore Drill Burnisher, Screw Drill, double Drill Countersink, glass drill and Straight Drill
Double margin, flat clearance construction produces reamer like finishes and resists walking when cutting aluminum castings, cast iron, cored holes and angular exits. Effective chip control up to 3.5 x Ø deep with flood coolant. High abrasion resistance carbide. Excellent tool life and easy to regrind four facet point. Straight flute, right hand cut. Step drill and coolant feeding designs available upon request. Allow 2.5 x Ø of flute for chip exit up to 14” (6.35mm), 2 x Ø up to 716” (11.1mm
Premium carbide grade provides excellent wear resistance when cutting cast aluminum, bronze, cast and ductile irons, titaniums, fiberglass, hard plastics and non-ferrous metals. Not recommended for soft steels. 135° four facet split point improves true position and is an excellent starting drill for longer coolant fed drills. 2 to 2.5 times faster speed than standard high speed steel with better hole finish. Right hand spiral, right hand cut, heavy duty high speed steel body. Allow 2.5 x Ø of
Carbide tip offers excellent abrasion resistance when drilling glass, tile, mirrors and ceramics. Precision ground spear point allows these fragile materials to be drilled with reduced cutting pressure to avoid cracking the material. 30 SFM using steady hand feed is recommended. Apply coolant generously or drill part submerged in a bath of lubricant. Right hand cut, high temperature braze.
Straight flute, right hand cut, heavy web construction is ideal for high accuracy hole drilling in hard metal parts over 40 Rc371 Hb and abrasive materials. 135° modified four facet notched thinned point. Submicron carbide grade. Produces reamer like hole finish, accurate hole size and can be used for coring out pre-existing holes. Clear chips frequently and leave 2 x Ø for chip exit. Also see die drill Styles 150 & 151. Shank Ø = Cutting Ø
Submicron carbide tipped coolant fed construction provides maximum wear resistance when cutting alloy steels, tools steels, free machining stainless steels, aluminum casting, bronze, cast iron and some nickel base high temperature alloys. Stub length and self centering 135° helical point eliminate the need for spot drilling. Body diameter reduced to eliminate galling. TiN coating adds lubricity and prevents edge build-up. Heavy web slow spiral for maximum feed rates and chip flow. Right hand spiral,
Brazed carbide tip on high helix masonry flute is ideal for the economic drilling of carbon, hard plastics, concrete, plaster, wall board, stone, brick and asphalt. Not recommended where precise hole sizing or close concentricity is required. Right hand spiral, right hand cut.
Coolant fed construction increases tool life and improves surface finish when reaming aluminum, cast iron, steels, plastics and other abrasive materials. Carbide tipped, high speed steel bodies. Use decimal size range column to determine the overall length, flute length and shank dimensions for Precision ground cutting edges. modified and grind down reamers. Polished flutes for smooth chip flow. Straight flute, right hand cut.
Submicron carbide grade provides maximum wear resistance when cutting high carbon, high alloy and stainless steels, titanium, high temperature alloys, aluminum, bronze, cast and ductile iron. Stub length and 140° double split point eliminates spot drilling and reaming in most instances. Heavy web, high helix flute clears chips effectively allowing up to five times greater penetration rate vs. standard high speed steel. Right hand spiral , right hand cut. See style 113 for steel cutting carbide grade.
Submicron carbide grade and Tail coating provides maximum wear resistance when cutting high carbon, high alloy and stainless steels, titanium, high temperature alloys, aluminum, bronze, cast and ductile iron. Jobber length and 140° double split point eliminate spot drilling and reaming in most instances. Heavy web, high helix flute clears chips effectively allowing up to five times greater penetration rate vs. standard high speed steel. Right hand spiral, right hand cut. See style 116 for steel
