Reamers Hand & Bridge High Speed Steel

* Reamer & Drill Selection Procedures
Selecting the correct reamer diameter is not quite as simple as one might think. Selecting the correct drill size

 is also important as doing so will prolong the life of your reamer and ensure proper size and finish. 

There are 3 steps involved in selecting the correct reamer and drill size for your application:

1) Determine the correct reamer diameter based on total hole tolerance and the machine ability of your material.
2) Calculate the correct hole diameter needed prior to reaming,
3) Select the proper drill diameter to make that hole.
An example follows each step.
 

Step #1: 
To calculate the correct reamer diameter, based on the machine ability of the material to be reamed, 

deduct the allowances in the following table from the maximum finished hole size:

For example: If your finished hole size is .5000 with a -.0005 +.0000 tolerance, and the material is 

302 Stainless (which has a machine ability rating of 50) the chart shows that the range to deduct is. 0004-.0005.

.5000 -.0004 = .4996
.5000 -.0005 = .4995
Therefore, the best reamer size is .4995

.0090.0024-.0056.0024-.0056
.0100.0027-.0062.0027-.0062

Step #2: 
Based on the reamer selected in step # 1, the following table shows the amount of stock that should be 

removed by the reamer (leaving the recommended amount will ensure the best finish and tolerance):

Using the same example (finished hole size is .5000 with a -.0005 +.0000 tolerance, and the material is 

302 Stainless (which has a machine ability rating of 50): 

the chart shows that the amount to deduct from the reamer size is .007-.015.

4995 -.015 = .4845 
4995 -.007 = .4925 
Therefore, the best hole size before reaming is between .4845 and .4925

.2501-.5000.012-.020.007-.015
.5001-1.0000.012-.020.010-.020

Step #3: 
Based on the pre-reaming hole diameter selected in step # 2, the following table shows the oversize 

allowance that should be deducted from the hole size to arrive at the correct drill size:

Using the same example (pre-reaming hole size is between .4845 and .4925 and the material is 

302 Stainless (which has a machine ability rating of 50): the chart shows that the amount to 

deduct from the  reamer size is .0048. 

4845 -.0048 = .4797 
4925 -.0048 = .4877
Therefore, the best practical drill size is 31/64 (.4844) because it is between .4797 and .4877 To recap 

in this example you should use a 31/64 drill and a .4995  reamer.
