Drilling and cutting tools including spade drills, drill inserts and holders

T-A^® Geometry
Standard Geometry
	AMEC's Standard T-A^® Geometry is an excellent choice for general purpose use. The design provides fast penetration rates that produce good hole size and finish. Standard geometry combines highly efficient, stable, cutting action to minimize power consumption. Recommended for use in most steels, cast irons, high temperature alloys and aluminum alloys. GRADES: HSS (CPM-M4, CPM-T15, Premium Cobalt), Carbide inch and metric C2 (K20) and C5 (P40) COATINGS: (TiN, TiAIN, TiCN) Sample Item Number: 0132A-0112

Flat Bottom (FB) Geometry (U.S. Patent No.: 6,135,681)
	AMEC's Flat Bottom geometry is used to flatten, or square the bottom of pre-existing holes. Tools with this geometry, are normally sized the same diameter as the hole. However, this style tool (when used with short length holders) may also be used to counterbore holes smaller than the tool diameter. The patented geometry provides efficient and stable cutting action. GRADES: HSS (CPM-T15) COATINGS: (TiN) Sample Item Number:152T-0112-FB

Cast Iron (CI) Geometry
	AMEC's Cast Iron geometry is specifically designed for use in gray and white cast irons. This special geometry provides exceptional edge strength and tool life. Includes AMEC's SK2 corner preparation. TiAIN coating is recommended. GRADES: Stocked in C3 with TiAIN coating Sample Item Number: 1C32A-0112-C1

SK2 (SK) Geometry
	AMEC's special corner preparation is designed to increase tool life by providing efficient, uniform heat dispersion at the insert corners.; Ideal for all materials. Sample Item Number: 132A-0112-SK

Corner Radius (CR) Geometry
	AMEC's special corner preparation is designed to increase tool life, as well as minimize exit burns. Provides excellent heat dispersion at the insert corners. Ideal for tougher applications in virtually all materials. Sample Item Number: 132A-0112-CR

*High Impact (HI) Geometry
	AMEC's high impact geometry is specifically designed to enhance chip formation in materials with high elasticity/ductility, and poor chip forming characteristics. Includes AMEC's SK2 corner preparation for increased tool life. Effective at improving chip formation in structural, cast, and forged steels, plus, cast stainless steel and high temperature alloys, particularly in materials above 200 BRN. Sample Item Number: 132A-0112-HI

*High Rake (HR) Geometry
	AMEC's high rake geometry is specifically designed to enhance chip formation in materials with high elasticity/ductility, and extremely poor chip forming characteristics, and low material hardness. This special geometry shortens chip length, improving chip control and evacuation from the hole. Includes AMEC's SK2 corner preparation for increased tool life. Recommended for use in most soft gummy steels, steel castings, and steel forging under a material hardness of 200 BRN. Sample Item Number: 132A-0112-HR

Brass (BR) Geometry
	AMEC's brass geometry is specifically designed for efficient drilling in brass. Our specialized geometry and edge preperation, provides excellent tool life and eliminates the tendency of the tool to self feed, as well as drill windup, in soft brass materials. Sample Item Number: 132A-0112-BR

Cam Point (CP) Geometry
	AMEC's special cam ground point geometry is designed to provide self-centering characteristics. The helical cam ground point provides efficient chisel edge cutting action, to produce outstanding drill stability. Recommended for use with standard and extended length T-A^® Holders on all materials, especially steels and cast irons, castings and forgings. Sample Item Number: 132A-0112-CP

Notch Point^®(NP) Geometry
	AMEC’s patent pending Notch Point^® geometry provides an excellent solution for reducing bell mouth and tool lead off. In addition the Notch Point^® geometry significantly reduces thrust while providing improved chip control. This new geometry may be applied to all standard T-A^® drill inserts and provides excellent stability for deep hole drilling applications. This geometry can also be utilized in combination with other geometry including Cast Iron, High Rake and High Impact geometry. (See sample item numbers below.) Sample Item Number: 132A-0112-NP Combination Geometry Item Numbers: Cast Iron Notch Point^®:1C32A-0103-CN High Rake Notch Point^®:132A-0012-RN High Impact Notch Point^®:132A-0012-IN

All special geometries not specified as stocked are available in all AMEC standard grades of material and coatings as a non stocked standard, requiring 2 to 3 weeks lead time. *not regrindable
