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

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.
