T-A ® Insert Grades and Geometries<br />
Specific Application Geometries<br />
To further enhance the versatility of the Allied Maxcut T-A ® <strong>Drilling</strong> System, specific application<br />
geometries are available, which will further improve customer's productivity. These geometries are<br />
designed and produced to exacting standards in AMEC manufacturing plants in Dover, Ohio, USA.<br />
Specific application geometries are available in all substrate grades and coatings, with a delivery<br />
lead time of 5/6 weeks.<br />
Enhanced Chip Control<br />
High Impact - HI<br />
• For materials with hardness over 200 Bhn (700 Nmm2 )<br />
• Enhances chip formation in materials with high elasticity/ductility and poor<br />
chip forming characteristics.<br />
• SK corner clip for improved tool life<br />
• Target materials, structural/cast and forged steels<br />
Availability: 5 - 6 weeks. All grades and coatings<br />
Ordering Code Example: 132T-35 HI<br />
High Rake - HR<br />
• For materials with hardness below 200 Bhn (700 Nmm2)<br />
• Improves chip formation in materials with very high elasticity/ductility,<br />
extremely poor chip forming characteristics, and low material hardness.<br />
• SK corner clip for improved tool life<br />
• Target material: Soft steels, steel castings and forgings<br />
Availability: 5 - 6 weeks. All grades and coatings<br />
Ordering Code Example: 132T-35 HR<br />
Improved Dimensional<br />
Accuracy<br />
Cam Point - CP<br />
• Helical cam ground point<br />
• Improved drill stability and centring characteristics<br />
• Reduction of bell mouthing when using longer holders<br />
• Improved hole finish when using longer holders<br />
• Target materials: Steels, cast/forged steels, cast iron<br />
Availability: 5 - 6 weeks. All grades and coatings. Y - 2 Series inclusive<br />
Ordering Code Example: 132T-35 CP<br />
Corner Enhancement<br />
Corner Radius - CR<br />
• Improved exit burrs<br />
• Improved surface finishes in some applications<br />
• Good heat dispersion, giving longer tool life in some applications<br />
• Can be used in conjunction with other geometries, i.e. Flat Bottom.<br />
Availability: 5 - 6 weeks. All grades and coatings<br />
Ordering Code Example: 132T-35 CR<br />
SK<br />
• Larger than standard corner clip<br />
• Improved heat resistance<br />
• <strong>Standard</strong> feature on CI, HI, HR geometries<br />
Availability: 5 - 6 weeks. All grades and coatings<br />
Ordering Code Example: 132T-35 SK<br />
Material Specific<br />
Brass - BR<br />
• Improved tool life due to our specialized geometry & edge preparation<br />
• Reduced self feed tendency<br />
Availability: 5 - 6 weeks. All grades and coatings<br />
Ordering Code Example: 132T-35 BR
