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
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
