How to Order our HSS Tools
The following pages consist of E-Z Burr's standard tool specifications. When
you determine which E-Z Burr tool is the right one for your application you
can either call us, email us or fax us.
When ordering High Speed Steel deburring tools whether it is a Micro Series
Tool, Standard HSS tool or Stubby Tool you will need to add a blade suffix to
the tool number.
Please reference page 23 to determine the correct blade suffix for your ap-
plication. These tool extension numbers are based on your desired hole size,
material and whether you need front and rear hole deburring or rear-only.
Example: EZL 0250 both Front and Rear Cutting = EZL0250-02
EZL 0250 Rear Only Cutting = EZL0250-08.
Note: Special blade cutting angles by quotation only. Standard blade cutting angle
is 45°. We can produce any blade angle required, from 30° to 70°. Please specify
F (Front) and R (Rear) blade angle for angles other than 45°.
