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.

The J100 Series are general purpose HSS straight shank drills with a black oxide finish. Ideal for applications involving steel (including cast steel) cast iron (including malleable cast iron) as well as nickel, brass aluminium alloys and graphite. Their 118° point allows for precise hole alignment and reliable cutting performance whilst the black oxide coating helps reduce heat by retaining coolant on the tool surface. The coating also helps reduce the risk of the tool staining.

Features and Benefits
• High speed steel construction for increased tool durability
• Point angle of 118° for precise holemaking and precision cutting
• Black oxide coating helps aid chip flow, reduce heat and prevent staining
• Ideal for applications involving steel, iron, nickel, brass, aluminium alloy and graphite

• Iron
• Nickel
• Brass
• Aluminium alloy
• Graphite

Notes
• Available in sizes 0.25mm -20.00mm

Standards
• Manufactured to BS 328/DIN338RN
