Carbide Drill With Twist Flute

For demanding machining applications that require efficient chip evacuation and excellent hole quality, the carbide drill with twist flute stands as a top-tier solution. Its helical groove design is engineered to pull chips up and out of the hole effectively, reducing heat buildup and preventing chip re-cutting. This makes it exceptionally suitable for a wide range of materials, from steels and stainless steels to cast iron and non-ferrous metals. When your project requires a different chip removal strategy, consider our Carbide Drill With Straight Flute for improved stability in certain brittle materials. For specialized depth requirements, our Carbide Drill For Deep Hole is optimized for extended reach. We also offer precision tools for specific hole types, such as the Carbide Drill For Blind Hole for accurate depth control and the Carbide Drill For Through Hole for clean, burr-minimized break-through.

The performance of a Carbide Drill With Twist Flute is defined by its precise engineering and premium material composition. Constructed from micro-grain tungsten carbide substrate and coated with advanced, multi-layer PVD (Physical Vapor Deposition) coatings like AlTiN or TiSiN, these drills offer exceptional hardness, wear resistance, and thermal stability. The precise flute geometry and point angle are critical for achieving superior surface finish, straightness, and dimensional accuracy. Key specifications that define its capability include:

• Cutting Diameter Range: Available from 1.0mm to 20.0mm.
• Overall Length (OAL): Standard lengths accommodate various depth-to-diameter ratios.
• Flute Length: Optimized for effective chip evacuation over the drilling depth.
• Shank Type: Straight shank or Coolant Through Shank for high-pressure coolant delivery.
• Point Angle: Typically 140° for versatile applications, with other angles available for specific materials.
• Helix Angle: A high helix angle (often 40°) for efficient chip removal in long-chipping materials.

Key Features

• Premium Carbide Material: Exceptional hardness and wear resistance for extended tool life.
• Twist Flute Design: Optimizes chip removal, reduces heat generation, and prevents clogging during deep or high-speed drilling.
• High Precision: Tolerances as tight as ±0.01mm, ensuring exact hole dimensions and alignment.
• Wide Material Compatibility: Suitable for metals, alloys, plastics, composites, and advanced materials.
• Versatile Applications: Ideal for automotive motor housings, robot parts, aerospace components, molds, and electronic components.
