TAPPING SPEED GUIDEProper tapping speeds are veryimportant in obtaining efficienttapping results. There are manyfactors which affect proper tappingspeeds, some of which are listedbelow and to the right.

MATERIAL FACTORS:• Thermo-conductivity of thematerial and wall thicknessas it affects heat dispersion

• Variations in carbon content of steel• Hard spots in material• Depth of hole to be tapped• Percentage of full threadto be tapped

TAP FACTORS:• Major diameters, pitch and lead• Style of tap• Width of lands• Amount of hook or rake• Length of chamfer• Bottoming taps normally requireslower speeds than plugchamfered taps

TAPPING SPEED GUIDE

36

Proper tapping speeds are determined best by experiment. In the table below, speeds shown shouldbe used as a guide only, and the suggested surface feet per minute adjusted upward or downwarduntil the best results are obtained.

MECHANICAL FACTORS:• Type of tapping machine and holder; speeds for small diameter taps are often governed bythe limitations of the machine

• Condition of tapping machine and spindle• Type of fixture; vertical or horizontal tapping (faster speeds for vertical tapping)• Method of feeding the tap• Cutting fluid used and method of application• The optimum speed for tapping is the highest speed that conditions permit,consistent with economic tool life

TAP/DRILL CHART-INCH

To minimize tapping problems and lengthentool life, use the largest drill possible toproduce a minor diameter that will resultin the lowest percentage of full threadconsistent with adequate strength. A minordiameter that provides a 55% to 65%thread is sufficient for most requirements,but in some cases a higher percentageof thread may be necessary to conformwith the minor diameter limits of the threadclass specified.

TAP DRILL SIZESDrills generally cut holes larger than theirdiameters. In the table to the right, theprobable percentages of full thread weredetermined by the average amount oversizethe various drills are expected to cut.

* Sizes given permit direct tapping withoutreaming the hole, but only give a fullthread for the first two or three threads

† For Dryseal Straight Pipe Threadssuggested drill sizes are as shown,except; 1/4" pipe, use .444 drill size

TAP/DRILL CHART-INCH

Formula: Percentage of Full ThreadThreads Per Inch x Major Dia. of Tap = Drill Dia.

.01299= Percentage of Full Thread

Example: Determine percentage of full thread for 2" – 12N Tap, using 1.9219" Drill.

2.0000-1.9219 = .0781 ÷ .01299 = 6.012Threads Per Inch = x 12

Theoretical Percentage of Full Threads = 72.144

Formula: Tap Drill Size

Major Dia. of Tap - .1299 x Percent of Full ThreadNumber of threads Per inch

= Drill Size

Example: Determine drill size for 2" –12N Tap, 70% Full Thread. Basic Major Diameter of Tap = 2.0000"

.01299 x 70 = .9093 ÷ 12 = .0758"Theoretical Drill Size = 1.9242"
