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

Suitable for precision grinding of carbide, gems, glass, ceramics, tough alloys, cermets, tool steels etc.

Features and Benefits
• Diamond grip mesh is 120/140 for cutting hard substrates
• Ideal for operating speeds of up to 15,000 - 30,000 rpm
• Range of cutting head sizes to suit application

Typical Applications
• Deburring
• Grinding
• Hard substrates

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

Designed with spiral flutes and various lengths and forms to give high quality centre holes that suit most applications. TiN coating on working parts for increased heat and wear resistance, offering a prolong efficient cutting lifespan.

Features and Benefits
• HSS construction for increased durabiluty
• TiN coating for increased heat and wear resistance
• Delivers high quality centre holes in most drilling applications

Typical Applications
• Drilling

Standards
• BS 328 : Part 2 : 1986,
• DIN 333A, ISO 866, ISO 2540, ISO 2541
