3/8" SD-3 Ball Shaped 1/4 x 6" Shank Burr

About this item:

• 3/8" SD-3 Ball Shaped 1/4 x 6" Shank Burr
• SD-3 Express cut tungsten carbide burr.
• 6.35mm x 150mm (1/4" x 6") Extended Shank.
• Express Cut Burrs (also referred to as Double Cut Burrs) are general purpose burrs designed for rapid stock removal and improved operator control.
• Chip size is reduced and lower tool speeds can be used compared with standard 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.
