Allied utilizes smart item numbers in which each character has a specific meaning. The item number for the question above is 152T-0102 where: 1 = T-A drill insert; 5 = Super Cobalt; 2 = Series 2; T = TiN Coating; 01 = 1” in whole numbers and 02 = diameter in 32nds (2/32 = 1/16, therefore, 0102 = 1-1/16” diameter). Product nomenclature can be found on each product page under the "Technical Information" section.
There is no minimum dollar value; however some items have minimum packaging requirements.
Yes, all inserts within a series are interchangeable in holders of the same series.
Yes, we accept credit card payments from Allied authorized distributors using MasterCard, VISA, American Express and Discover Card.

All T-A® series Y, Z, 0, 1, and 2 inserts are sold in two-piece packages. Series 3 and larger are sold in single quantities. Reference the T-A® Drill Insert Nomenclature under the "Technical Information" section on the T-A® product page for series identification.
Allied manufactures drill inserts within the diameter range of 0.374 to 4.500 inches. Diameters outside of this range can be produced pending evaluation of the request. Please see the Special Tools Design Section of the on-line catalog for details.
Series 0.5, 1.5 or 2.5 holders have a significantly higher inertial strength over the series 0, 1, or 2 holders. Higher inertial strength provides an increased level of rigidity during use.
The drill insert range for each series 0.5, 1.5 or 2.5 holder is shown in the holder section of the T-A® Drilling Products section (A30) in the catalog. Insert diameters specific to half series holders are also listed in the T-A® insert tables.
It depends on the application of the tool. Standard holders with a Morse taper shank have a seat for an RCA. If the tool is being used in a rotating application and the customer needs to provide coolant flow from an external coolant line, then an RCA is required.
T-A® drills and holders are a unique design that belong exclusively to Allied. HP drills interchange with all manufacturers’ Universal Style holders that meet ANSI B94.94 -1975 TYPE 1 specifications.
T-A® drill inserts are better because they provide lower cost per hole and increased performance that justify the cost of T-A® holders. HP drills are recommended when a customer already has a Universal Style holder and they are drilling a limited number of holes.
Yes, every chance we get! A Guaranteed Tool Test application (click here for form) must be submitted prior to testing to ensure the test environment is properly specified. After reviewing the customer’s information, Allied’s Engineering Department will recommend speeds and feeds before the tools are shipped for testing. Allied requires a comprehensive test report after tool tests are completed, regardless of results.
Both products have distinct advantages. Allied T-A® drill inserts and holders offer the lowest cost and highest performance drilling solutions. HP drill inserts have many of the same performance benefits as T-A® drill inserts, but they cover a different size range (Universal style holders accept a wide variety of both Universal and HP type inserts that are available from stock).
Yes! Oil hole or standard twist drills can be replaced with either T-A® or HP products. Indexable carbide drills should be replaced when horsepower, hole depth, hole size or insert breakage is a problem. Indexable carbide drills limit machine performance because they require stricter operating specifications. Allied T-A® and HP drills can be run at a wider variety of speed and feed rates to best utilize a customer’s machine capacity. Please refer to the Allied Recommended Speeds and Feeds chart for a performance comparison.
Yes, however, it is not normally recommended. Allied drills are center cutting and designed to drill from solid material. Pilot holes and spot drilling are not typically required. If spot drilling is performed, a tool with an included angle greater than or equal to that of the Allied drill should be used. This allows the chisel point of the Allied drill to contact the work piece first, thus providing a stable entry.
No, peck drilling can be utilized if necessary. A lack of chip control or difficulties with chip evacuation due to low coolant pressure or volume indicates peck drilling may be required. However, Allied offers a wide variety of tool geometries to provide chip formation in a wide variety of materials, eliminating the need for peck drilling in most applications.
