Gun Drilling Tools Ordering

Gun drilling tools ordering is influenced by many factors. Those must be stated clearly for buying right gun drilling tools. The most important factors includes drilling diameter, material to be drilled, overall length of tools, shank (driver) code.

Drilling Diameter

Drilling diameter always related choice of bits’diameter. Right diameter of drilling bits makes deep hole with correct diameter. And also important for tolerance control. 

Material to be Drilled

As a kind of machining, gun drilling deals with almost all kinds of metal material. But not all of them share the same drilling tools even though the drilling diameter and depth is the same.

Different material has different hardness, chip break ability, etc which may ask for gun drilling tools with different grinding angle, manufacturing technology ,etc.

Overall Length Calculation

gun drilling tools dimension

Overall length maybe the most important factor when you buy a gun drilling tool.

How to calculate the length is as bellowing.

L= total length of gun drill from end of shank to very top of bit

L1=effective length

D= diameter of drill bit

H=shank length

W=drilling depth

LA=grinding reserve

LB=width of guide system

L2= minimum chip removing distance

Overall Length L=LA+W+LB+L2+H

Shank Code of GSM

Shank is connected with drilling spindle to drive gun drilling tools to rotate. So it is also named as driver. 

The shank type is various based on connection method, diameter, etc. For easy option, there’s shank code.

GSM code is based on industrial manufacturing standard. You can directly choose the code bellowing. If there’s no code meets your needs, GSM provides OEM service in term of your drawing.
