Package contents 1 pack — 10.8 mm drill bit Key specifications Diameter: 10.8 mm Overall length: 142 mm (5.59') Flute length: 75 mm (2.95') Point angle: 135° splitpoint for reduced walking and faster center penetration Material: M42 cobalt speed steel (8% cobalt) Coating: Titanium nitride (TiN) for improved wear and corrosion resistance Why this drill bit solves problems Reduced walking and improved accuracy: the 135° splitpoint starts on contact, so holes are more precise without the need for pilot marks. Long life under heavy use: M42 HSS with 8% cobalt provides hardness, heat resistance, and crack resistance for drilling strength and difficulttomachine metals. Better surface performance: TiN coating reduces wear and corrosion, prolonging tool life and maintaining cutting performance at RPM. Consistent cutting in mixed materials: designed to cut metal, hardwoods, composite boards, plastics, and carved components without rapid dulling. Performance and compatibility Ideal for RPM drilling; cutting edges hold sharpness during sustained use. Balanced toughness and wear resistance makes these bits suitable for handheld drills and automated or volume machining equipment. Compatible with standard drill chucks that accept a 10.8 mm shank diameter. Practical applications (use scenarios) Metalworking: drilling holes in strength alloys or stainless steel fasteners where reduced walking and heat resistance are required. Woodworking and furniture making: precision mortiseandtenon joinery, drilling through dense hardwoods such as rosewood or teak, and cutting clean holes in thin wood sheets. Craft and carving: detailed carving work and drilling in composite boards and carved components where edge retention at RPM is important. Benefits summary Precision starts and cleaner holes thanks to the 135° splitpoint Extended service life (3–5× longer than standard HSS in many conditions) lowers cost per hole Durable in demanding environments due to M42 cobalt steel and TiN coating Versatile across metal, wood, and plastic applications What you get One 10.8 mm, 142 mm overall length, 75 mm flute length, M42 cobalt HSS drill bit with 135° splitpoint and TiN coating — a robust choice for accurate, longlasting drilling in demanding materials.
