Precision Drill Rod Datasheet
O1 Oil Hardening
|Carbon 0.90||Vanadium 0.20|
|Manganese 1.20||Chromium 0.50|
The most widely used grade of drill rod. It is a general purpose tool steel, outstanding for its reliability in hardening, good wear resistance, and excellent toughness.
W1 Water Hardening
|Carbon 0.95 to 1.10|
Water hardening grade is intended to meet the needs of the machine shop for average work
wherever better grades of tool steel drill rod are not required.
A2 Air Hardening
|Carbon 1.00||Vanadium 0.25|
|Molybdenum 1.10||Chromium 5.25|
A2 is recommended rather than O1 when increased wear resistance, safer hardening, and less distortion are required.
S7 Air Hardening Super Shock
|Carbon 0.50||Molybdenum 1.40|
|Silicon 0.25||Chromium 3.25|
A new outstanding air-hardening drill rod – the toughest, strongest drill rod for so many jobs that require maximum strength and impact.
D2 High Carbon – High Chrome
|Carbon 1.50||Molybdenum 0.75|
|Chromium 12.00||Vanadium 0.25 to 0.80|
An air-hardening type steel, known for its maximum wear resistance qualities. It is ideal for use in tools, dies, etc., used in long production runs.
M2 Moly-Tungsten-High Speed
|Carbon 0.83||Chromium 4.15|
|Molybdenum 5.00||Vanadium 1.90|
The most widely used type of high-speed steel and, in general, can be used for the same
applications as T-1 high speed. Its higher carbon content and balance analysis produce
properties applicable to all general-purpose high-speed uses.
Fine Standard Tolerances
|Round Drill Rod|
|3.000″ to 0.500″||+/- .0010″||.005″||+1/8″, -.0|
|0.499″ thru 0.125″ dia.||+/- .0005″||.005″||+1/8″, -.0|
|0.124″ and smaller||+/- .0003″||.005″||+1/8″, -.0|
|*Closer tolerances than standard can be produced upon special request.|
