√FEATURE:
The drill bit is made of 4341 high-speed steel material, it has high and wear resistance, suitable for processing medium materials
Gold finish can further enhance the drill bit's wear and corrosion resistance, thereby extending its service life.
The 135° split point tip drill provides excellent processing stability and is well-suited for harder materials. It effectively reduces the risk of cutting-edge chipping, thereby improving drilling efficiency and hole quality.
√APPLICATION:
The 4341 hss drills are suitable for light-duty machining; applicable to low-carbon steel, aluminum alloy, brass, cast iron, medium-carbon steel, stainless steel, acrylic, plastic, wood, etc. For machining thicker metals, low RPM + flood coolantare required.

√NOTE:
When machining different materials, the spindle speed and feed rate vary.
Generally, the harder the material, the lower the spindle speed and feed rate need to be.
Position the twist drill at 90° to the workpiece.
For thick materials, drill in multiple passes to prevent overheating or breakage.
For large holes, start with a guide hole.
Use coolant to improve efficiency, extend tool life, and reduce material damage.
For specific speed and feed rates recommended for common materials, please refer to the details provided on the product page.
