Oval Shape.
All sizes are nominal with a 6mm shank unless other wise stated.

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.
• 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.

These carbide burrs are designed for cylindrical end cutting of low feed, high speed materials. Available in a variety of sizes with varying cut capabilities.

Features and Benefits
• Manufactured from durable carbide for tool longevity
• Rapid cut (Cut 3) burrs are suited for use on softer non-ferrous and plastic materials
• Chipbreaker (Cut 9) burrs are suited for use on cast iron, carbon steel, alloy steel 50RC and 60RC
• Suitable for deburring and polishing of cast iron, cast steel, carbon steel, alloy steel and stainless steel up to HRC65 hardness
• Ideal for light stock removal at high rpms

Typical Applications
• Deburring

Notes
• Not suitable for milling large amounts of material
• 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

Series J100 - Metric general purpose drills for steels, cast steel, grey cast iron, malleable cast iron, nickel brass, aluminium alloy and graphite.

Features and Benefits
• High speed steel construction with bright finish for increased toughness
• Supplied in the as-ground condition for use with non ferrous materials

Standards
• Manufactured to BS 328/DIN338RN

Notes
• Drills with a bright finish are supplied in the as-ground condition and such tools are used generally in the machining of non-ferrous materials.
