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

Typical Applications
• Cutting and drilling
• Hard metals
• Stainless steel
• Bronze

Notes
• Available in sizes 1-13mm

A­ chatter-free cutter giving an excellent burr-free finish. Capable of deburring and countersinking in one stroke with no ‘back-off’ of tool.
Also free countersinking of aluminium with no secondary bulge. For special applications and exotic materials, a choice of hard coatings is available.

The HSS-Co 5% Countersink 6 Piece Set features high performance, multi flute countersinks in various sizes.

Features and Benefits
• Manufactured from high speed steel and cobalt for improved strength
• Straight shank design with bright finish for improved performance on ductile metals
• Supplied in a robust carry case for easy and secure portability
• straight shank design
• 90° ground flute angle provides optimal cutting performance with an inclusive angle of 90°

Standards
• Manufactured to BS328:Part 5:1983

Contents
• 1x 8, 10, 12.5, 16, 20 and 25mm

Typical Applications
Deburring
Chamfering

Crosscut and double cut to improve control and chipbreaks. Manufactured from high grade tungsten carbide for general-purpose use. Suitable for deburring and polishing of cast iron, cast steel, carbon steel, alloy steel and stainless steel etc.
up to HRC65 hardness.

Features and Benefits
• Hard carbide construction for increased cutting hardness
• Crosscut and double for improved chip control and chipbreaks
• Suitable for deburring and polishing of materials up to HRC65 hardness

Typical Applications
• Deburring
• Polishing

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
