Drill and Cut Sideways to Enlarge Holes — These serrated side cutting drill bits function as a drill saw bit, allowing controlled side cutting after drilling to enlarge existing holes, shape openings, and create simple slots in wood and plastic. Designed for DIY woodworking, repairs, and creative modifications where standard twist drill bits cannot easily modify the shape or size of an opening.
TITANIUM-COATED HSS DRILL BITS — This twist drill bit set combines high-speed steel construction with a titanium coating for wear resistance. Spiral flutes help clear chips during drilling in soft wood, plywood and plastic, supporting everyday woodworking, repairs and craft projects.
Versatile for Woodworking, DIY Projects, and Home Repairs — Whether you are building furniture, repairing PVC pipes, or working on craft projects, these multi-material drill bits handle everyday drilling and hole modification tasks. The 12-piece set covers 5 practical sizes: 2 each of 1/8 inch and 5/16 inch, 1 of 5/32 inch, 3 of 3/16 inch, and 4 of 1/4 inch, so you always have the right size from small drill bits to larger ones for common DIY needs.
Get Optimal Results with the Right Side-Cutting Method — For optimal side-cutting results, drill a starter hole first, then use larger sizes such as 1/4 inch and 5/16 inch. Maintain sufficient drill speed; if your drill stalls when moving sideways, the RPM is too low. Apply light, controlled pressure. Do not use thin bits (1/8 to 3/16 inch) for side cutting as they may snap under lateral force. Optimized for soft wood, plywood, and PVC; not recommended for drywall, hardwood, or metal.
3X Longer Lifespan: Multi-edge cutting technology spreads wear evenly, tripling your drill bit’s life. Save money on frequent replacements.
Accurate Holes: No Wobble, No Mess – minimal radial runout ensures clean, perfectly round holes every time. Ideal for precision metalwork operation.
1.5X Faster Drilling Speeds: Experience drilling speeds 1.5x faster than standard drill bits. HighFire's precision engineered geometry without jamming or stalling. Perfect for high-volume jobs where speed matters.
All-in-One Functionality: Skip Pilot Holes – Drills large diameters in one step, eliminating the need for center drill and pilot drill bits. Faster setups, fewer tools to carry.
