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
