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

Features and Benefits
• Solid carbide construction
• Enables fast stock removal on hard materials
• Allows for improved control and reduced chips

Typical Applications
• Deburring
• Polishing
• Cast iron
• Cast steel
• Carbon steel
• Alloy steel
• Stainless steel
up to HRC65 hardness.

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.

Range includes 1xD, 1.5xD and 2xD lengths (ISO Metric threads). Our quality inserts are now supplied in packs of 10 or 50. Other sizes and lengths are available on request, please ask for further information.

The Kennedy range of HSS-Co heavy duty straight shank jobber drills provide durable and reliable cutting performance at high temperatures and speeds thanks to the addition of 5% cobalt to their alloys. Their toughness and heat resistance allows them to to drill steels with tensile strength up to 1,400 N/mm², very hard bronze, stainless steels as well as heat and acid resistant steels.

Long lasting the cutting edges retain their sharpness for longer periods, maximising performance and productivity, whilst also being resistant to corrosion.

Features and Benefits
• Made with a 5% cobalt alloy for optimal performance at high speeds and temperatures
• Allows for optimal cutting of metals up to a tensile strength up to 1,400 N/mm²
• 135° point angle for precise hole making and efficient cutting
• For applications including steel, bronze, stainless and acid resistant steels
• Extended lifespan on cutting edge, required less sharpening over time
• Excellent corrosion resistance extends the lifespan of the tool

Standards
• Manufacturing Standard: BS 328, DIN 338B
