Jobber Drill, 4mm, Normal Helix, Cobalt High Speed Steel, Bronze Oxide

Description

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/mm?, 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/mm? | • 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 | | Specifications | • Point angle: 135? | • Helix angle: normal | • Web thickness: strengthened | • Relief angle: normal. | • Tolerance of diameter: h8 | • Tolerance of shank: f11 | • Supply unit.
