Notes
• It may be necessary to adjust the display rate to achieve the best
performance.
• Harder materials require slower speeds.
• Smaller burs require faster speeds.
• Extra long burs (>150 mm long) require a slower speed.
• Keep moving and gently press while in use.
• Running at slower than optimal speed will encourage chips.
• Running at a speed higher than optimal will cause tooth wear.
• Making the tool too hot may cause the braze to melt and separate
the bit from the shank.
• The use of worn tools and chucks will encourage debris.
• Do not sink the bur more than one-third of its periphery.
