Key Features:
| Parameter Category | Key Specifications & Details |
|---|---|
| 1. Basic Geometry | Diameter: 0.01mm to 100mm+; Point Angle: 118°, 135°, 90°; Helix Angle: 10°~40°. |
| 2. Shank Type | Round Shank, Hex Shank, Morse Taper (MT), SDS Shank. |
| 3. Material & Coating | HSS, Carbide, PCD; Coatings: TiN, TiCN, TiAlN, DLC. |
| 4. Tolerance | H7 (precision), H8/H9 (general); Runout ≤0.01mm. |
Workpiece Selection: For hard materials like stainless steel, choose carbide bits with 135° split points. For soft materials like aluminum, opt for high helix angles and DLC coatings to prevent adhesion.
