# 3/8″ Compression Bit Technical Specifications
## Tool Overview
**Type:** Compression Router Bit
**Application:** FRCNC Machining
## Specifications
### Cutting Geometry
– **Flute Count:** 3 flutes
– **Cutting Diameter:** 3/8″ (0.375″)
– **Cutting Length:** 1″
### Physical Dimensions
– **Shank Diameter:** 3/8″
– **Overall Length:** 3″
### Operating Parameters
– **Feed Rate:** 1000 IPM (Inches Per Minute)
– **Spindle Speed:** 21,000 RPM
## Application Notes
### Material Compatibility
Compression bits are ideal for:
– Laminated materials
– Veneered panels
– Melamine-faced boards
– Plywood
– MDF with laminate surfaces
### Key Benefits
– **Clean Top and Bottom Surfaces:** Compression design pulls chips toward center, preventing tear-out on both faces
– **3-Flute Design:** Provides excellent chip evacuation and smoother finish
– **High Feed Rate Capability:** 1000 IPM allows for efficient production speeds
### Recommended Usage
– Ensure proper chip evacuation when cutting at high feed rates
– Use appropriate spindle speed based on material type
– Ideal for full-depth cuts in sheet goods up to 1″ thick
– Consider multiple passes for materials thicker than cutting length
### Storage & Maintenance
– Store in dry environment to prevent corrosion
– Clean after each use to remove resin and debris
– Inspect cutting edges regularly for wear
– Sharpen or replace when performance degrades
