1/2" Ultra-Bor HSS Premium Jobber Drill Bit 135º pt. - 6 per Pack

Viking Ultra-Bor style Bully Heavy-Duty Jobber length fractional drill bits excel in demanding applications. The 135° split point design is self-centering and self-starting, preventing the drill bit from walking on the material surface and eliminating the need for a center punch or pilot hole. Black and Gold surface treatment provides additional lubricity, reduces wear and assists swarf in traveling along the flutes with less resistance as it exits the hole during drilling. Positive chuck grip is achieved with the 3-Flats on shank design, making the bits ideal for use in hand- held drills with Jacobs style keyed or keyless chucks. Made in America using high moly alloy tool steel, the heavy-duty construction of Bully Super Premium bits makes them ideal for use with hard metals, work hardening grades of stainless steel, and other difficult to drill materials.

3-Flats on Shank design only offered on sizes 3/16” and above.

• Substantially longer cutting life. Nitro-carburized flute has increased Rockwell hardness
• Cuts harder materials. The 135° point takes a smaller chip. More torque is directed to a smaller area. Can drill into materials with hardness of over 30 on the Rockwell "C" scale
• 135° Split Point prevents drill walking giving accurate hole starting without the use of a center punch
• Holds tighter hole size. The split point design is self centering, limiting the normal oversize drilling characteristics
• Polished and Ground with a Black and Gold Surface treatment for increased lubricity and lower drilling effort
• 3-Flats on shank stops chuck slippage and provides a positive chuck grip
• Made in the USA

For best results with any cutting tool always use a cutting fluid or lubricant whenever possible. Always clamp or secure in place the item being drilled, unsecured small or light parts can spin violently while being drilled, causing injury. Always wear ANSI/CSA approved protective eyewear when using any tool.
