HSS multi diameter step drills produce good quality holes in a wide variety of sheet metal, using either a bench drill or light pedestal drilling machine. Manufactured from high speed steel, they offer sound rigidity, strength and stability when machining. Each tool cuts parallel holes in a range of specific sizes and is compatible with materials up to 1/8" (3mm) thick.

Features and Benefits
• High speed steel construction for greater strength, rigidity and stability
• Excellent wear and heat resistance for prolonged tool life
• Cuts parallel holes in sheet metal

Typical Applications
• Drilling
• Sheet metal

Notes
• Available sizes 1-12mm to 6-37mm

Series L100 HSS straight shank long series drills are excellent general purpose drills which are designed to drill steels with tensile strength up to 1,000N/mm2, cast steel, grey cast iron, malleable cast iron, nickel brass and graphite.

Features and Benefits
• Manufactured from HSS for improved toughness
• Black oxide coating for greater heat and wear resistance
• Ideal for general purpose drilling

Typical Applications
• Drilling
• Steels
• Grey cast iron
• Malleable cast iron
• Nickel brass
• Graphite

Standards
• Manufactured to BS 328; Part 1: 1986, DIN 340 RN, ISO 494.

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.
• 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 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
