Sutton Tools R40 Uni Drill

Product catalog summary

Overview
The R40 UNI SPM Drills are designed for high-performance drilling across a wide range of materials, particularly steels with hardness up to 1300 N/mm². These drills feature a 130° four-facet point, a 40° helix, and a parabolic flute shape, which together provide increased stability and accuracy for drilling straight holes up to 3 times the diameter without pecking.

Key Features

Rigid and strong design suitable for various materials.
Endmill type plain shank with h7 tolerance for use in collet chucks.
SPM material with 10% Co content offers greater toughness than carbide and higher performance than HSS Co.
TiAlN coating for longer tool life and reduced friction.

Benefits

Capable of drilling 3 times the diameter without pecking, reducing cycle times.
Self-centering with a web-thinned point for enhanced performance.
Suitable for production drilling as an alternative to carbide drills.
Effective for materials up to 1500 N/mm².

Technical Specifications

Catalogue Code: D155 (Stub), D168 (Jobber)
Material: SPM
Surface Finish: TiAlN
Geometry: R40°
Point Type: 130° 4 Facet Form B
Shank Tolerance: h7

Performance Comparison
The R40 UNI Drill outperforms universal carbide drills in certain applications, offering lower tool costs and shorter cycle times. For example, in drilling AISI-P20 material, the R40 UNI Drill operates at a cutting speed of 45 m/min and a feed rate of 358 mm/min, with a cutting time of 3.4 seconds.

Material Compatibility
The drills are suitable for a variety of materials including steels, stainless steels, cast irons, coppers, aluminums, and plastics. Specific feed rates and cutting speeds are provided for different material types to optimize performance.

Notes on Drilling

Step feeding or pecking is required for drilling greater than 3 times the diameter.
Reduce drilling speed by 20% when drilling cast or black surfaces.

Formulas

n = (vc × 1000) / (Ø × π)
vc = (Ø × π × n) / 1000
vf = f × n

Conclusion
The R40 UNI SPM Drills provide a cost-effective and high-performance solution bridging the gap between carbide and HSS drills, suitable for small batch sizes and less than perfect machines.
