Gewi U-Drill Insert
Model: SPMT090408-QD GW1328
High-Efficiency Chip Breaking & Evacuation
- Excellent chip control: Optimized chipbreaker design breaks chips into small pieces for easy evacuation.
- Enhanced coolant performance: Internal coolant holes enlarged by 1.5×, ensuring better cooling and smooth chip evacuation.
- Benefit: Prevents chip entanglement, ensures continuous machining, and significantly improves drilling efficiency.
Wide Versatility & Compatibility
- Common specification: SPMT090408 is a widely used U-drill insert size, suitable for a variety of drill diameters.
- Flexible matching: Compatible with different U-drill holders based on machining needs.
- Machine adaptability: Can be used on machining centers, CNC lathes, and conventional lathes, offering broad applicability.
Four Cutting Edges for Cost Reduction
- Dual-function design: Works as both center and peripheral cutting edge.
- Four usable edges: 2 inner + 2 outer = 4 cutting edges per insert.
- Economic advantage: Reduces tooling cost compared to single-edge or double-edge inserts.
Material & Coating
- Substrate: High-strength carbide substrate for toughness and impact resistance.
- Coating: Advanced PVD coating, ensuring superior wear resistance and thermal stability.
- Applicable materials: General-purpose for steel, stainless steel, and cast iron.
- Overall benefit: Improved cutting performance and extended tool life.
Precision Machining Accuracy
- Optimized geometry: Provides stable cutting and smooth machining.
- High dimensional accuracy: Ensures precise hole size and superior surface finish.
- Flat-bottom drilling: Produces relatively flat blind hole bottoms, eliminating the need for pilot holes or flat drills.
- Benefit: Higher accuracy, improved efficiency, and simplified process flow.
