Dovetail Mill Application: SDM Series is specifically engineered for dovetail slot machining in machine tool guides, mold slides, and mechanical fitting surfaces. Available in two coating versions: TiSiN for steel (≤38HRC) and DLC for aluminum/non-ferrous. The 4-flute design ensures superior surface finish.

Two Optimized Versions for Different Materials

Steel Version (TiSiN Coated)

  • Coating: TiSiN (Titanium Silicon Nitride)
  • Hardness Range: ≤38 HRC
  • Best For: Carbon steel, alloy steel, stainless steel (≤38HRC)
  • Key Benefits: High heat resistance, wear resistance, prevents built-up edge

TiSiN coating provides excellent heat resistance and wear resistance for steel dovetail machining up to 38HRC. Ideal for machine tool guide ways and mold slide surfaces.

Aluminum Version (DLC Coated)

  • Coating: DLC (Diamond-Like Carbon)
  • Material: Aluminum, copper, brass, graphite
  • Key Feature: Ultra-low friction coefficient (<0.1)<>
  • Benefits: Zero material adhesion, 3-5x tool life extension

DLC coating provides ultra-low friction to prevent aluminum and copper adhesion during dovetail profiling. Essential for precision dovetail slots in non-ferrous materials with clean, burr-free finish.

Why Choose SDM Dovetail End Mills?

 
Precision Dovetail Geometry

Accurate 30°, 45°, 60° angles with ±0.5° tolerance. Ensures proper fit and smooth sliding motion in machine tool guides and mold components.

 
4-Flute Surface Finish

4-flute design provides superior surface finish compared to 2-flute tools. Reduces vibration and improves dovetail slot quality for precision fitting.

 
Dual Coating Options

Choose TiSiN for steel (≤38HRC) or DLC for aluminum. Each coating optimized for specific material properties and dovetail machining conditions.

 
Neck Design for Deep Slots

Reduced neck diameter enables machining of deep dovetail slots with minimal interference. Critical for machine tool guide way applications.

Material Compatibility Guide

Steel Version (TiSiN Coated)
Workpiece MaterialHardnessSuitabilityNotes
Carbon Steel / Alloy Steel≤38 HRC◎ ExcellentPrimary application. TiSiN prevents built-up edge. Use moderate speeds with flood coolant.
Stainless Steel (304, 316)≤38 HRC◎ ExcellentGood machinability. 4-flute design ensures smooth dovetail finish.
Pre-hardened Steel≤38 HRC◎ ExcellentHigh wear resistance. Ideal for mold slide and guide way machining.
Aluminum / Copper-✗ Not RecommendedUse Aluminum Version (DLC). TiSiN not optimized for non-ferrous.
Aluminum Version (DLC Coated)
Workpiece MaterialHardnessSuitabilityNotes
Aluminum (6061, 7075, 5052)-◎ ExcellentPrimary application. DLC prevents adhesion. Use high RPM with air blast.
Copper / Brass / Zinc-◎ ExcellentDLC coating prevents smearing. Ideal for precision dovetail slots.
Graphite / Carbon-◎ ExcellentIndustry standard for graphite electrodes. No coating contamination.
Steel / Hardened Steel>25 HRC✗ Not RecommendedDLC coating fails rapidly in steel. Use Steel Version (TiSiN).

◎ = Excellent | ✗ = Not Recommended |        SDM Series offers two specialized versions. Choose based on your workpiece material.

Typical Applications for SDM Dovetail End Mills

Machine Tool Guide Ways

Precision dovetail slot machining for CNC machine tool guide ways and sliding surfaces. TiSiN coating ensures clean dovetails without built-up edge.

Mold Slides & Cores

Dovetail profiling of mold slides, inserts, and core components. DLC coating ensures burr-free surfaces for smooth mold operation.

Aerospace Fittings

Dovetail slot machining of aluminum and steel aerospace structural components and fitting surfaces. Consistent angle accuracy meets strict standards.

CAM Setup & Dovetail Machining Guidance

Steel Version Parameters (TiSiN)
  • ✅ Carbon Steel: Vc = 80–120 m/min, fz = 0.04–0.10 mm/tooth, ae = 0.2D–0.4D
  • ✅ Stainless Steel: Vc = 60–100 m/min, fz = 0.03–0.08 mm/tooth, ae = 0.2D–0.4D
  • ✅ Use climb milling for smooth dovetail finish
  • ✅ Use flood coolant for heat management
Aluminum Version Parameters (DLC)
  • ✅ Aluminum 6061: Vc = 400–800 m/min, fz = 0.05–0.15 mm/tooth, ae = 0.3D–0.5D
  • ✅ Copper/Brass: Vc = 200–400 m/min, fz = 0.03–0.10 mm/tooth, ae = 0.2D–0.4D
  • ✅ Use climb milling for clean dovetail profiling
  • ✅ Use air blast or MQL for chip evacuation
Best Practices for Dovetail Mills
  • ⚠️ Select correct angle - 30° for shallow dovetails, 45° for standard, 60° for steep profiles
  • ⚠️ Use light radial engagement - dovetail mills are not designed for heavy slotting
  • ⚠️ Maintain consistent feed - avoid dwell to prevent work hardening
  • ⚠️ Runout<0.005mm<>- essential for maintaining coating integrity and angle accuracy
  • ⚠️ Use climb milling - reduces cutting forces and improves surface finish
  • ⚠️ Select correct version - Steel (TiSiN) for steel, Aluminum (DLC) for non-ferrous

Factory Production & Quality Control

Dovetail end mill grinding and quality inspection

  • 🔹 Traceability: Batch tracking with laser marking. ISO 9001 certified quality management.

Frequently Asked Questions

Dovetail end mills are specialized tools for machining dovetail slots, commonly used in machine tool guides, mold slides, and mechanical fitting surfaces. The SDM series offers 30°, 45°, and 60° angles for different dovetail profiles.

DLC coated version is optimized for aluminum and non-ferrous materials with ultra-low friction to prevent material adhesion. TiSiN coated version is designed for steel up to 38HRC with high heat resistance and wear resistance.

Yes, but you must select the correct coating version. Use DLC coated for aluminum and non-ferrous materials. Use TiSiN coated for steel up to 38HRC. Using the wrong coating will result in poor performance and reduced tool life.

Yes. While we stock standard 30°, 45°, and 60° angles, we can manufacture custom angles, extended lengths, and specific shank diameters upon request. OEM branding and private packaging are available for bulk orders (MOQ 50+ pcs).
