ORDERING INFORMATION
The most common method of ordering consists of giving us: Quantity. Bushing type. The inside Diameter (A) (or drill size), the Outside Diameter (B) and the Length (C) of bushings or liners required. Please note that head liners are measured overall. 

Example:                     Bushing         I.D.       O.D.      Length
                 Quantity        Type          (A)         (B)           (C)
                  __________________________________________

                     24                 P                 5/16       5/8           3/4

Or, using the ANSI symbols assigned to the various sizes listed in the catalog:

Example: 24 P 40-12-5/16

ALL BUSHINGS WILL BE CONSIDERED TO BE FINISH GROUND. When ordering an unground O.D. specify unground and add the letter "U" to the ANSI symbol, or after the bushing type. The example shown is for 24 headless press fit bushings with a 5/16 I.D. or drill size with a 5/8 O.D. outside diameter and 3/4 inch length.

STANDARD SIZES: All bushing sizes listed herein are considered to be Catalog Standard Sizes and should be ordered whenever possible. Standard drill sizes, specified in the bushing I.D. range columns, are those standard letter, number, and fractional sizes defined by the American National Standards Institute and listed on the inside back cover of this catalog. Any other decimal or millimeter size within a given range is considered special and will be priced accordingly.

ANSI STANDARDS: The United States of America Standards Institute (USASI) is now known officially as the American National Standards Institute (ANSI). All former USA Standard bushings are now identified as ANSI Standard bushings.
Order tooling components by the All American catalog number listed.
Example:             Quantity                Catalog#
                           ______________________

                                25                     #107-50
All American personnel will be happy to help you convert other manufacturers' numbers to the All American number where possible.

ORDERING METRIC DRILL BUSHINGS:
Please order by giving us part number and inside diameter. Head press fit and head liner bushings are measured by overall length. Use the ANSI part number assigned to the various sizes listed in the catalog. Example given is for a headless press fit bushing with a 8 mm inside diameter, 12mm outside diameter and 16 mm length.

Example: PM-12-16-8 I.D.

GUARANTEE
All American Drill Bushings and Tooling Accessories are guaranteed against defects in material and workmanship and are warranted to be accurate to ANSI and catalog standards. Our liability is limited to replacement of any All American Drill Bushing part.

DISCLAIMER NOTICE: All American takes great care to ensure that the dimensions and specifications in our catalogs and flyers are correct but accepts no responsibility for printing and typing errors which unfortunately do sometimes occur. Our liability is limited to the replacement of any All American item. We at All American also reserve the right to change any dimension or specification without notice.

I.D. TOLERANCES: All American & ANSI Standard:

STANDARD SIZES: Standard sizes in a given I.D. range are sizes listed in the decimal equivalent chart either as a fraction, number or letter size. Any other decimal or millimeter size within a given range is considered special and will be priced accordingly.

To order: Specify type and "reamer bushing". Reamer
bushings will be furnished with correct tolerance on all
fraction, number, letter, and decimal sizes.
(Priced as specials.)

I. D. TOLERANCES: Metric

CONCENTRICITY: ( Total indicator reading ).

Standard ANSI bushings:
               I.D. 1/8 thru 1/2               0 to .0003 T.I.R. max.
            Other sizes                      0 to .0005 T.I.R. max.

Standard ANSI metric bushings:
             All sizes                         0 to .012MM T.I.R. max.
The above tolerances will be met at the drill exit end.

COUNTERBORE: Bushings with small holes are counterbored leaving correct drill bearing to facilitate chip removal and lubrication.

NO COUNTERBORE: Bushings normally counterbored may be ordered without counterbore by specifying "No Counterbore" or using abbreviation "NCB." (Priced as specials.)

RADIUS: All bushings feature a blended radius at the drill entrance unless otherwise specified.

LEAD: All press type bushings feature a concentric ground lead in addition to a chamfer on exit end of bushing.

STEEL: Our bushings are manufactured from selected steels known for their long wear and stability. Bushings are also available from other materials at extra cost (bronze, M-2, D-2, A-2, stainless steel, etc.)

HARDNESS: Rockwell C 62 - 64 in the hole.

CHIP CLEARANCE: Due to the abrasive action of metal particles, sufficient clearance should be provided between the drill bushing and the workpiece to allow for removal of chips. Careful consideration of this point will aid in producing accurate holes. (A rule of thumb is the greater the clearance the greater chance of error.) Example: The recommended chip clearance for metal producing small chips, such as cast iron, equals one-half the drill diameter. The recommended chip clearance for metals producing long chips, such as cold-rolled steel, equals one to one and one-half times the drill diameter. Maximum Accuracy: Use drill bushings of different lengths to obtain the combined advantages of adequate chip removal and precise accuracy. Example: Use a drill bushing that is short enough to provide chip clearance during the drilling operation. Next, use bushings long enough to contact or closely approach the work piece for the reaming operation.
