Straight-Flute Drill Bits
Available524 products
Straight-flute drill bits are stronger than spiral-flute drill bits and resist breaking when drilling into hard and abrasive materials, such as hardened steels with a Rockwell hardness of 35 to 60 HRC. The bits provide free-cutting action, generate minimal heat during drilling, and leave a smooth finish on the hole without requiring a reaming pass. The bits' straight flutes help with chip evacuation in horizontal drilling applications.

Bright Finish Solid Carbide Straight-Flute Drill Bits
The bright finish on these straight-flute drill bits is unaffected when the bits' cutting edges are resharpened. Carbide drill bits provide excellent hardness, wear resistance, and heat resistance. They require a rigid setup such as a drill press.

Bright Finish Carbide-Tipped Straight-Flute Drill Bits
These straight-flute drill bits have a bright finish that is unaffected when the bits' cutting edges are resharpened. Carbide-tipped drill bits have carbide cutting edges that provide excellent hardness, wear resistance, and heat resistance. The bits' body is made from a material that absorb more vibration and shock than carbide, so they are less rigid and less likely to break than solid carbide drill bits. These bits are used in machine setups.

Coolant-Through Bright Finish Carbide-Tipped Straight-Flute Drill Bits
These straight-flute drill bits have a bright finish that is unaffected when the bits' cutting edges are resharpened. Carbide-tipped drill bits have carbide cutting edges that provide excellent hardness, wear resistance, and heat resistance. The bits' body is made from a material that absorb more vibration and shock than carbide, so they are less rigid and less likely to break than solid carbide drill bits. These bits are used in machine setups.These drill bits have holes that allow coolant to flow to their tip to reduce heat and help clear chips during drilling.
