Wood Drill Bit , Iran
Wood drill bits are crafted from high-carbon steel or High-Speed Steel HSS. Their standard diameter varies from 2 to 50 millimeters. Overall bit length is designed between 60 to 300 mm based on application. The cutting lip angle is typically 60 degrees with a 118-degree point angle. Spade bit edges are ground with a 10-degree relief angle. The flute helix depth is approximately 0.25 times the bit diameter. This design enables efficient evacuation of long wood chips. Brad point bits feature a central spur for precise positioning. Surface hardness of heat-treated HSS bits reaches 64 Rockwell C.
The bit structure comprises a cutting tip, guiding body, and shank. Standard hex shanks measuring 1.5 to 13 mm are used for hand drills. Industrial bits often feature straight shanks with 6 to 12 mm diameters. Forstner bits have two peripheral lips and a central flat cutter. A titanium nitride coating of 3 microns triples tool life on some models. Recommended cutting speed for softwood is 3 to 6 meters per minute. For hardwoods, this speed reduces to 2 to 4 meters per minute. These bits can create holes with positional accuracy of 0.1 millimeters.You can order and buy Wood Drill Bit from Iran by contacting us through whatsaap and email.

How to Select Wood Drill Bit Size and Type
Selecting a wood drill bit depends on required diameter and operation type. Use standard twist bits for small holes up to 10mm. Bit diameter must exactly match screw or nail diameter. For holes larger than 25mm, spade or hole saw bits are recommended. Wood type is also influential. For softwoods like pine, bits with a sharp 60-degree point angle are suitable. For hardwoods like oak, use bits with a 90-degree point angle. Hole depth should be at least 15 percent deeper than the screw length. Optimal rotational speed is 3000 RPM for softwood and 1500 RPM for hardwood. Always use sharp, high-quality high-speed steel bits.
