uxcell 3mm Left Hand Twist Drill Bits for Metal (2pcs)

Product Overview: Carbide Twist Drill Bits

Material Composition
Our drill bits are crafted from premium YG6X carbide (tungsten steel) featuring a fine grain structure. This material is exceptionally hardened, achieving up to 91HRA, which imparts superior wear, corrosion, and heat resistance, alongside commendable bending strength.

Design Features
The drill bits incorporate a spiral chip space design that ensures efficient and clean chip removal. Paired with sharp cutting edges, these bits provide a smooth cutting experience, minimizing the likelihood of glitches or stickiness during operations.

User-Friendly Operation
These drill bits are optimized for use on machining centers and CNC lathes. However, it is advisable to refrain from using them with hand drills. Hand drills tend to vibrate, leading to instability that can cause the drill bits to break or twist off.

Key Characteristics
- Durability: The carbide tools boast an extended tool life and offer faster cutting speeds compared to other materials; however, they are more brittle due to their higher hardness. - Efficiency: The carbide composition is engineered for reliable cutting performance, ensuring high work efficiency throughout various applications.

Versatile Applications
These drill bits are suitable for both semi-finish and finish cutting tasks involving a range of materials, including stainless steel, alloy steel, cast iron, titanium alloy, non-ferrous metals, copper, and plastics. They are particularly effective for drilling abrasive materials while maintaining precision. Additionally, they can be utilized in high-temperature drilling scenarios and can accommodate various cooling conditions such as oil mist, water, oil, or air cooling.

Operational Tips
To maximize tool lifespan and enhance performance: - Ensure that the tool is clamped with a longer length within the chuck, as this minimizes vibrations. If shorter lengths are unavoidable, reduce both the feed rate and cutting speed to mitigate potential damage. - Choose an appropriate feed rate and cutting speed in accordance with the material being processed to achieve better accuracy and performance.
