Irwin 15-Piece Titanium HSS Fractional Jobber Drill Bit Set (4935607)
The Irwin 15-Piece Titanium HSS Fractional Jobber Drill Bit Set (4935607) is a comprehensive collection of drilling bits engineered for consistent performance in metal. This set features bits made from high-speed steel with a specialized titanium nitride coating, designed to reduce friction and heat buildup during use. This coating helps the bits maintain their cutting edge significantly longer than standard drill bits, ensuring a prolonged service life. The set includes a range of 15 fractional sizes, from 1/16 in. to 3/8 in., providing a versatile selection for a wide variety of drilling tasks.
KEY FEATURES AND BENEFITS:
Long-Lasting Performance: Each bit is coated with titanium nitride (TiN) to resist heat and friction, extending the cutting edge life up to six times longer than traditional high-speed steel bits.
Precise, No-Walk Starts: The 135-degree split-point tip is self-centering and starts drilling on contact with less force, preventing the bit from slipping and ensuring accurate hole placement from the start.
Enhanced Grip and Stability: All bits 3/16 inch and larger have a 3-flatted shank for a secure, non-slip grip within the drill chuck, preventing bit spin and improving drilling efficiency.
Convenient and Organized Storage: Comes in a durable, rubber over-molded case with an automatic indexing system that keeps all bits in their designated place for easy selection and safe transport.

Select the Right Bit: Choose the drill bit size that matches the hole diameter you need.
Secure the Bit: Loosen the drill’s chuck, insert the bit, and tighten securely. Ensure it is centered and stable.
Prepare the Surface: Secure the material you are drilling. Marking the location can help improve precision.
Begin Drilling: Position the bit on the mark and start drilling at low to medium speed with steady pressure.
Maintain Speed and Pressure: Increase drill speed as the bit begins to cut. Periodically withdraw the bit to clear chips and prevent overheating.
