uxcell Solid Carbide Twist Drill Bits 2.8mm, Metric Left Hand Spiral Flutes for Stainless Steel, 2pcs

uxcell Solid Carbide Twist Drill Bits 2.8mm, Metric Left Hand Spiral Flutes Straight Shank Tungsten Steel Drilling Tool for Stainless Steel Alloy Metal, 2pcs

uxcell Solid Carbide Twist Drill Bits 2.8mm, Metric Left Hand Spiral Flutes for Stainless Steel, 2pcs

Constructed from fine particle YG6X carbide (tungsten steel), the drill bit is hardened up to 91HRA, wear resistance, corrosion resistance, heat resistance, and good bending strength. Spiral chip space design for fast and clean chip removal. Sharp cutting edge provides smooth cutting and no glitches. Chip removal is not easy to stick to the tool. Use on machining centers, CNC lathes. Not recommended to be used with a hand drill. Hand drill is easy to shake, with poor stability, which makes drill bit easy to twist off. Used for semi-finish and finish cutting of stainless steel, alloy steel, cast iron, titanium alloy, non-ferrous metal, copper, plastics. Suitable for drilling abrasive materials when drilling accuracy must be maintained. Can be used in high temperature drilling applications. Adapt to several kinds of cooling conditions, such as oil mist, water, oil, air cooling. The longer the length of the tool clamped by the chuck, the better. If the clamping length is shorter, you need to lower the feed rate and cutting speed to reduce vibration and extend the tool life. Combined with the material to be processed, select an appropriate feed rate and cutting speed to improve the tool life and obtain better processing accuracy and performance.

Key Features

• ✅ Twist Drill Bits: Drilling Diameter: 2.8mm / 0.11"; Flute Length: 25mm / 0.98";Overall Length: 50mm / 1.97". Spiral chip space design for fast and clean chip removal. Sharp cutting edge provides smooth cutting and no glitches.
• ✅ Wide Applications: Used for semi-finish and finish cutting of stainless steel, alloy steel, cast iron, titanium alloy, non-ferrous metal, copper, plastics. Designed for drilling abrasive materials when drilling accuracy must be maintained.
• ✅ Carbide Tool: Constructed from fine particle YG6X carbide (tungsten steel), the drill bit is hardened up to 91HRA, wear resistance, corrosion resistance, heat resistance, and good bending strength.
• ✅ Features: Carbide tool offers long tool life and faster cutting speeds than other substrates, and it is higher hardness but is more brittle. Carbide material with good cutting performance, can ensure high work efficiency.
