Understanding the Smart Tool Number

The Fullerton Smart Tool numbering system can be very daunting at first glance. We want to make it easier on you and break it down so you can get a better understanding. First we will go through our non-standard, or special, products. These are our Z# Descriptions.






The first two digits are the code for the type of tool.

ZB = Special Burr (Special Rotary File)

ZD = Special Drill/Porting Tools/Form Tools with Drill Point

ZE = Special End Mill/Chamfer Mills/Wood Routers

ZF = Special STEP End Mill/Porting Tools/Form Tools with Drill Point

ZG = Special STEP End Mill/Chamfer Mills/Wood Routers

ZK = Special Keyseat Cutter

ZM = Special Miscellaneous/Countersinks/Boring Tools/Dovetail

ZR = Special Reamer/Form Tool/Counterbore

ZS = Special Saw

ZT = Special STEP Reamer/Form Tool/ Counterbore




Digits 3-6 indicates the series of tool (GDRL used for G-drills).




Digits 7-11 are the diameter, “D” represents a decimal place and means the tool is under 1”, a number here means the tool is over 1”. For step tools, the smallest diameter is to be used.




Digits 12-16 are the date. “08” is the year, “176” is the day of the year.




Digit 17 indicates who created the number; each person charged with creating numbers has a set of numbers or letters assigned to them.




Digits 18-20 are for revision levels.

Blank = original or no revision

A, B, C = revision level

Add X1 for test revision

_99 = regrind

_98 = rework
