The Kennedy® variable pitch hole saws deliver high quality holes in a range of materials, including wood, steel, brass, bronze, and cast iron. The M3 HSS cutting teeth aggressively cut to give a very smooth finish with little to no tear out.

Features and Benefits
• Cuts up to 40% faster than constant pitch saws
• Varying tooth pitch disrupts harmonics to substantially reduce noise
• Tooth life is extended when used in conjuction with a cordless drill

Typical Applications
• Construction
• Engineering
• Maintenance

Notes
• 4-6 teeth per inch
• 28.5mm (11/8") cutting depth

Swiss+Tech HSS Straight Shank TiN Tipped Jobber Drills are coated in a durable Titanium Nitrile at the tip for optimal tool life and performance when undertaking cutting applications. Their ground flute construction and bright body gives a more precise finish and therefore better cutting precision, making them ideal for use with steel, cast steel alloyed and non-alloyed, grey cast iron, graphite and malleable cast iron.

Features and Benefits
• Hardy TiN tipped coating for optimal performance and prolonged lifespan
• Bright body with ground flutes offers excellent precision when cutting
• 118° for excellent positional accuracy

Standards
• Manufactured to BS 328, DIN 338

Notes
Suitable for the machining of:
• Steel and cast steel (alloyed and non-alloyed)
• Grey cast iron, graphite and malleable cast iron
• Available in sizes 1.0mm - 16mm

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
