M2 HSS Center Drill Bits Overview<\/h2>\n

These Type A, double-ended center drills are intended for making center holes in workpieces held between centers and for controlled hole-starting operations. The supplied dimension chart lists 12 cutting diameters from 1.0 to 10 mm, with matching shank diameters of 4\u201325 mm and overall lengths of 35.5\u2013100 mm. The product title specifies M2 high-speed steel; confirm the grade, point geometry and finish for the ordered model, because the older product description lists several alternative steel grades and surface treatments.<\/p>\n

Key Configuration<\/h3>\n
\n
\n
\u25ce<\/div>\n
Type A Center Profile<\/div>\n

The illustrated form has a pilot and countersink on each end. Confirm the specified included angle and center-hole standard for the ordered model.<\/p>\n<\/div>\n

\n
\u2194<\/div>\n
Two Cutting Ends<\/div>\n

Both ends are shown as usable. Protect the unused end in the holder and verify adequate grip and clearance before machining.<\/p>\n<\/div>\n

\n
\u2195<\/div>\n
Size-Matched Shank<\/div>\n

Each cutting diameter has a corresponding shank diameter and overall length in the 12-size chart. Check holder fit before ordering.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

Key Product Advantages<\/h3>\n
\n
\n

Center-Hole Preparation<\/h4>\n

Creates a center feature for workpieces machined between centers.<\/p>\n<\/div>\n

\n

Double-Ended Design<\/h4>\n

Allows the second end to be used after the first end wears, if the tool remains serviceable.<\/p>\n<\/div>\n

\n

12 Listed Sizes<\/h4>\n

Cutting diameters from 1.0 to 10 mm, each with specified shank and overall dimensions.<\/p>\n<\/div>\n

\n

Grade and Finish Options<\/h4>\n

Confirm M2 grade and the requested finish; other grades and coatings belong to separate options.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

\n

Centering Applications<\/h3>\n

Use the center drill to prepare center holes in turned parts or to establish a controlled starting location where the subsequent drilling process requires it. The supplied product image lists carbon steel, 45# steel, die steel and aluminum alloy as example workpieces. Select cutting data and coolant for the exact material grade, machine rigidity and tool configuration.<\/p>\n

Application Note:<\/strong> The source image recommends coolant and avoiding overly aggressive cutting. Do not infer a guaranteed center-hole depth or finished-hole accuracy from the dimension chart.<\/div>\n<\/section>\n
\n

Workpiece Material Selection<\/h3>\n

The source image names carbon steel, 45# steel, die steel and aluminum alloy as examples, without defining workpiece hardness or tool-specific cutting data. Provide the exact grade, hardness and center-hole requirement when selecting the M2 tool, finish and coolant strategy.<\/p>\n<\/section>\n
