CCMT Turning Inserts

80° Rhombic Insert

Insert Grade QX5030
(ISO P20-P40 M20-M30) CVD Coated. - Medium / rough turning and intermediate cutting of steel / stainless steel. Combination of toughest substrate and alumina coating (MT-TiCN + TiC + AL2O3 + TiN) having superior chipping resistance provide wide coverage.

Chip Breaker: PM. Application: Med Cut.

Cut 6 carbide rotary burrs feature a crosscut and double cut to improve control and chipbreaks. Manufactured from high grade tungsten carbide for general-purpose use.

Features and Benefits
• Manufactured from carbide for greater hardness
• Cut 6 crosscut and double cut to improve control and chipbreaks
• Suitable for use on hard materials up to HRC65 hardness

Typical Applications
• Deburring
• Cast iron
• Cast steel
• Carbon steel
• Alloy steel
• Stainless steel

Notes
• Work piece and tools should always be steady and well supported
• Carbide burrs are not suitable for 'milling' large amounts of material, they are for light stock removal and high revolutions 'LOW FEED - HIGH SPEED'
• Always ensure that at least 70% of the shank length is clamped by the collet or chuck of the tool being used
• Always ensure that the tool is rated to the recommended operating speed of the burr

Cut 6 - Double Cut.

Cut 9 - Chipbreaker
Chipbreaker fast stock removal for improved control and reduced chips for use on hard materials, i.e. steel alloy 50RC, 60RC, carbon and cast iron.

Suitable for deburring and polishing of cast iron, cast steel, carbon steel, alloy steel and stainless steel etc.
up to HRC65 hardness.

Please note:
• Work piece and tools should always be steady and well supported.
