Tool Geometry: Cut and Spiral
Every week we have conversations with customers about how to customizetool designs to help achieve ideal machining...

We work with customers who serve a wide range of industries – medical device, aerospace, automotive, defense, firearms, rapid prototyping, mold making, and more. Although specific needs vary by industry, a common goal is to reduce cycle times. Whether part of a cost reduction initiative or as a way to increase output, reducing cycle times through tool design can be achieved in many different ways.
With so many tool options to consider, how does a person decide where to start? For most of our customers, we begin with an email or a short phone call to better understand the application and determine what is important to achieve. With or without tool prints, our technical team can suggest tool options that may help to reduce cycle times and accomplish key initiatives.
How does this play out?
EXAMPLE 1
Application: COMPANY A wants to achieve shorter cycle times by increasing material removal rates
Material: Ti-6Al-4V
Tool type: 6-Flute High Performance End Mill
Coating: AlTiN
MITGI mix:
- Tapered core for increased rigidity
- Variable helix geometry dampens vibration and improves part finish
- Geometry optimized for full axial depth of cut in dynamic or trochoidal milling strategies
- Radial relief provides a stronger edge that can better withstand high feed rates
Add-on Request: COMPANY A would like to increase tool life thereby reducing overall project costs
MITGI recommendation: Upgrade to NACO coating. This coating will provide added heat resistance and more lubricity. This low-cost upgrade will deliver longer tool life
EXAMPLE 2
Application: COMPANY B has a turning application and wants to create a grooved feature and establish feature height in a single plunge
Material: Inconel
Tool type: 2-Flute Coolant Thru Trepan Tool
Coating: AlTiN
MITGI mix:
-
Two holes deliver coolant to the cutting edge, thereby reducing heat and removing chips
-
Custom coolant thru design increases tool life while cutting inside of a bore where coolant wouldn’t normally reach
-
Custom design ensures consistent results and form accuracy
Add-on request: COMPANY B wants to reduce chances of chipping
MITGI recommendation: Add edge break by introducing a small radius, therefore reducing the chance of premature chipping.
