Bordo Xtreme Burr 1/2 SA-5 Cylindrical 1/4 Shank Burr

About this item:

• 1/2" SA-5 Cylindrical 1/4" Shank Burr
• Xtreme Performance Tungsten Carbide Burr
• 6.35mm (1/4") Shank.
• Bordo Xtreme burs remove up to 75% more stock on Mild Steel during the first 5 minutes of grinding when tested against other leading premium-quality double cut burs.
• Cumulative stock removal on Stainless Steel over 15 minutes is over 50% more than Express Cut burrs.
• Ideal for use in carbon steel, cast iron, high strength steel, stainless steel, steel castings, steel welds, titanium alloy and fibreglass composite.
• Harder materials require slower running speeds.
• Smaller burrs require faster running speeds.
• Long shank burrs require slower speeds for safety reasons.
• Apply constant movement and light pressure when using the burr.
• Running below the optimum speed will cause chipping.
• Running above optimum speed will cause premature tooth wear.
• Allowing the burr to become too hot may cause the braze to soften, and cause the head to become detached from the shank.
• Using tools and collets which have become worn will cause chipping.
• Do not sink the burr for more than one third of its periphery.
