Plain Shank
Spiral flute, 3 flute. Medium duty. Used for milling of pre-drilled holes to allow bolt or cap head screws to lie flush with the component surface. Manufactured to manufacturers standard

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

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
