Xtorque XTO55MM 5.5mm Heavy Duty HSS COBALT Drill Bit

Xtorque XTO55MM 5.5mm Heavy Duty HSS COBALT Drill Bit

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° 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% 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: 5.5mm
• 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
• More 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)
