Product Overview

This customized 3-flute carbide end mill performs both rough milling and finish milling operations without tool changes, specifically designed for cutting MDF and plywood materials.

DLC Coating Advantages for Woodworking

Ultra-Low Friction: Coefficient of friction <0.1 reduces heat buildup in resinous materials
Non-Stick Surface: Prevents pitch/resin adhesion (critical for MDF and plywood glue lines)
Enhanced Hardness: 3,000-4,000 HV (vs. 1,500-2,000 HV for standard carbide)
Chemical Inertness: Resists corrosive compounds in treated wood and adhesives

Tool Geometry Optimization

Parameter	Specification	Rationale
Flute Count	3 flutes	Balances chip load and evacuation
Helix Angle	35°-45°	Reduces harmonic vibration
Rake Angle	12°-15° positive	Aggressive material removal
Edge Prep	0.05-0.1mm hone	Prevents edge chipping

Cutting Parameters (CNC Router Applications)

Material	RPM	Feed Rate (IPM)	DOC (×D)	WOC (×D)	Chip Load (IPT)
MDF	18,000-22,000	400-600	1.0-1.5	0.3-0.5	0.008-0.012
Plywood	16,000-20,000	350-500	0.8-1.2	0.25-0.4	0.007-0.010
Hardwood	14,000-18,000	300-450	0.6-1.0	0.2-0.35	0.006-0.009

Note: D = Tool Diameter; DOC = Depth of Cut; WOC = Width of Cut

Special Design Features

Anti-Vibration Grooves: High-frequency dampening slots (patented designs available)
Hybrid Cutting Edge: Combination of shearing (upper) and scraping (lower) geometry
Thermal Barrier: 2µm AlOx interlayer between DLC and substrate

Performance Comparison vs. Standard Tools

Metric	DLC-Coated	Uncoated Carbide	Improvement
Tool Life	800-1,200 hours	200-300 hours	300-400%
Surface Ra	0.8-1.2µm	1.5-2.5µm	40-50%
Resin Buildup	0.1mg/hour	1.2mg/hour	92% reduction

Maintenance Protocol

Cleaning: Use alkaline-based tool cleaners (pH 9-11) every 8 operating hours
Inspection: Check for micro-chipping with 20× magnification weekly
Reconditioning: Professional edge re-honing recommended after 400 hours
