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

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

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
