Flat-Bottom Drill Bits

Available4 products
Flat-bottom drill bits create holes with flat bottoms. The bits shear material as they drill a hole, which minimizes burring at the hole's exit and leaves a smooth finish on the hole. This often eliminates the need for a finishing pass after drilling. Flat-bottom drills are also used for counterboring holes, drilling holes at an angle, and creating intersecting holes and half holes. They can be used for drilling inclined and rounded surfaces, shoulders, or thin plates.

Coolant-Through TiAlN-Coated Solid Carbide Screw-Machine Length Flat-Bottom Drill Bits

Coolant-Through TiAlN-Coated Solid Carbide Screw-Machine Length Flat-Bottom Drill Bits
These drill bits have a TiAlN coating that withstands high temperatures and protects the bits from wear during high-speed, dry machining applications with difficult-to-machine ferrous metals. Carbide drill bits provide excellent hardness, wear resistance, and heat resistance, but they require a rigid setup such as a drill press. These drill bits have holes that allow coolant to flow to their tip to reduce heat and help clear chips during drilling. Screw-machine length drill bits are shorter than jobber length and maintenance length drill bits and can access tight spaces where longer drill bits cannot fit. They provide more strength and rigidity and can drill straighter holes than longer drill bits.
