Dovetail End Mill

Overview

Dovetail End Mills are designed to machine accurate dovetail slots and undercuts on CNC equipment. Made from ultrafine-grain solid carbide with material‑specific edge preparation and coatings, they deliver stable cutting and clean finishes in a wide range of materials.

Advantages

• Accuracy and repeatability: Ground on advanced CNC grinders with tight geometry control and low runout. Consistent slot dimensions and smooth sidewalls support reliable production.


• Substrates and coatings: Ultrafine‑grain carbide provides rigidity and edge retention. Coating options include TiAlN/AlTiN for alloy and stainless steels, TiCN for abrasive materials, and ZrN or DLC for aluminum and non‑ferrous alloys.


• Stable geometry: Optimized rake and relief, balanced cutting edges, and neck‑relieved shanks help reduce vibration and deflection in tight features.


• Verified quality: ISO9001 and SGS processes with in‑process inspection, dimensional reports, and traceable batches.

Product Range

• Standard profiles: Included angles of 45°, 50°, 55°, 60°, 82°, and 90°. Metric and inch tip widths, common shank diameters, and OALs for mainstream holders. Options include 1–3 cutting edges, relieved necks, and corner radii or chamfers.


• Micro tools: Sub‑millimeter to 3 mm tip widths for miniature mechanisms and precision slideways. Tight concentricity and tailored edge prep produce burr‑free micro features.


• Extended reach and necked designs: Provide clearance in deep cavities and undercuts while controlling deflection.


• Material‑optimized versions: Polished edges with ZrN or DLC for aluminum and other non‑ferrous metals. Reinforced, TiAlN/AlTiN‑coated cutters for hardened steels and nickel alloys.


• Custom tools: Non‑standard angles, step forms, asymmetric flanks, coolant‑through shanks, and specific tip widths. Designs are engineered per drawing or sample.

Applications

• Precision slideways and fixtures: Accurate angles and stable sidewalls for smooth sliding contact and robust workholding features.


• Aerospace, medical, and mold components: Clean undercuts and form features in stainless, titanium, and hardened tool steels.


• Woodworking and composites: Specialized profiles and coatings help reduce tear‑out and resin buildup.

Selection Guide

• Angle: Match the included angle to the mating part (e.g., 60° for general use; 82° or 90° for locking features or countersink compatibility).


• Tip width and depth: Choose a width that meets the required land while maintaining rigidity. For deep undercuts, use neck‑relieved designs to prevent shank interference.


• Reach: Minimize overhang. Select extended‑reach or necked variants for narrow pockets and deep cavities.


• Material pairing: Aluminum/non‑ferrous—polished edges with ZrN or DLC, high RPM, light radial engagement. Alloy/hardened steels—TiAlN/AlTiN, prioritize rigidity, lower radial DOC; use coolant‑through when heat control is critical.


• Programming tips: Favor climb milling, maintain low runout with precision toolholding, and use multiple light passes on steep angles.

Quality and Documentation

Each tool is inspected for dimensions, angle verification, and cutting‑edge integrity. Reports and traceable batches support consistent results across orders.

Setup Recommendations

Use high‑precision collet chucks or equivalent holders to minimize runout and improve finishes. Preset on certified equipment to confirm protrusion, angle clearance, and reach before machining.

Ordering and Lead Time

Specify included angle, tip width, major/minor diameters, shank diameter, OAL, neck length, edge radius or chamfer, coating, and coolant‑through requirements. Standard items ship promptly; custom profiles follow a clear schedule with batch‑level inspection. Contact us to discuss your application or request a quotation.
