Its VARIABLE HELIX™ Design enables fast material removal with an aggressive 35° helix angle that tapers to 15°, improving efficiency. The 135° SPLIT POINT TIP™ ensures precise starting and reduces walking, while the 3-Flat Secure-Grip™ design keeps the bit firmly in place within the chuck. Additionally, the QUADEDGE TIP™ helps prevent heat build-up, allowing for extended use and reliability in tough drilling conditions. Model Number: 48-89-2305
