Description
Features:
- Suits DIY to tradesman
- Ideal for every job
- Trade tough
- For drilling metal, wood and plastic
- Industrial quality for drilling stainless steel and other tough materials
- 135 degree Split Point Enables accurate positioning and less drilling pressure
- Colour tempered finish enables identification of cobalt drills
- 5% cobalt formula improves abrasive & heat resistance, for increased strength at higher drilling temperatures
- Constructed of M-35 5 percent cobalt high speed steel for super abrasive resistance in tough metals
- Cobalt steel extends cutting edge life and maintains cutting life after resharpening
- Extra hard drill for greater wear
- Reduced shank above 3/8″ allows the use of larger drill bits in a 3/8″ chuck
- Rubber over molded case protects kit if dropped
- Tap & Drill selection chart for convenient reference.
- Automatic indexing for easy bit access and identification
- Removable cartridges: easy to carry bits from case to work site
- Preferred drill for harder materials, especially stainless steel
Specifications:
- Size: 15mm
- Material: Cobalt Steel
- Precision ground from solid cobalt alloyed high speed steel
- Higher cobalt alters the material characteristics by increasing the hardness and high resistance to abrasion
- Suited to drilling materials that have high toughness and tensile strength, such as cast iron, bronze, weld seams and stainless steel
- Suited to CNC machines, Pillar Drills and Drill Presses due to the brittleness of the material compared to standard HSS
- Hold their rigidity and hardness at a higher temperature than HSS drill bits
- Split points (self centering points)
