We features a wide variety of the finest quality Carbide Burrs, made of premium micro grain carbide, and carefully ground on state of the CNC grinders. Carbide burrs and rotary files are used in various applications for deburring, cylinder head porting, mold making, tool and die, metalworking, tool grinding, foundry, aerospace, automotive, dental laboratory, wood carving, farriers, metalsmithing, sculpting, welding, chamfering, jewelry manufacturing, die casting, and metal casting.
Basic Fluting Styles for Carbide Burs:
Cut #6: Double Cut: Very efficient stock removal. Creates a small chip. Good finish. Excellent operator control.
Cut #3: Single Cut: General purpose fluting. Produces long chips.
Cut #1: Nonferrous: For nonferrous materials. Aggressive stock removal.
Cut #3SP: Chip Breaker: Provides breakdown in chips. Better control.
Cut #4: Diamond Cut: For heat treated and tough alloy steels where control is important. Creates a power-like chip. Excellent finish.
Cut #2: Coarse Cut: Provides large flute area for softer ferrous materials. Fast stock removal.
Cut #5: Fine Cut: For general use on hard materials requiring a fine finish.
For more stability, insert the accessory bit all the way into the tool and then back it out slightly before tightening down the collet nut or keyless chuck. Do not use these for drilling holes or for enlarging holes that are less than twice the diameter of the cutter. The tungsten carbide surface can easily catch the side of a hole and break the bit.Use higher speeds for hard woods, slower speeds for metals and very slow speeds for plastics (to avoid melting at contact point).Start at lower speed. Then increase to the speed that gives the most favorable results.Do not apply excessive pressure, it can slow the spindle and chip cutting edges, let the bur do the cutting. Use the sides of the cutter for effective cutting. The tip cuts poorly and can break under pressure. Never in-capsulate the bur in the cut. If chattering occurs, increase speed.When using in aluminum, and magnesium, consider some form of lubricant, wax, or tallow, as it will help prevent the flutes from loading or packing. Carbide burs, if used properly will out perform HSS burs by 50:1
