Storm 3000 Series Carbide End Mill – Full Specifications

Storm 3000 Series – Complete Size Chart and Specifications

Getting the right cutter means going beyond brand preference. Diameter, shank, length of cut, and overall length all change how a tool performs in the cut, and with tough materials, a wrong choice shows up fast. The Storm 3000 series end mill specifications are laid out here in full so machinists can make that call with confidence, not guesswork.

Storm 3000 Series Overview

The Storm 3000 Series is built around a 3-flute square end profile, HD eccentric relief, and a 60 helix carbide end mill design that keeps chip flow moving cleanly through the cut. These tools were developed for shops running stainless steel, titanium, Inconel, and nickel-based alloys that punish an underprepared cutter quickly.

The 60° hi-helix geometry isn't just a spec number. It pulls chips out faster, reduces heat buildup at the edge, and keeps the cut cleaner longer. That translates directly to better surface finish and longer tool life in difficult materials.

Key design points:

  • 3-flute square end construction.
  • 60° high-helix geometry.
  • Free-cutting flute design.
  • HD eccentric relief for cutting-edge support.
  • Corner radius options for stronger edge profiles.
  • Suited for stainless steel, titanium, Inconel, and nickel-based alloys.

For buyers reviewing stainless steel end mill specs, the details that matter most are diameter, shank, LOC, OAL, flute count, relief style, and coating. Each one plays a role in whether the tool performs or wears out before the job is done.

Storm 3000 Series – Standard Sizes (3-Flute Square End)

These are the standard 3 flute carbide end mill sizes in the Storm range. Each listing gives the full set of dimensions so machinists can match the cutter to the actual job setup rather than work around a tool that doesn't quite fit.

When working through the chart, keep these points in mind:

  • DIA sets the cutting width, which drives most other decisions.
  • SHANK needs to match the holder or collet exactly.
  • LOC tells you how deep the tool can cut in a single pass.
  • OAL controls reach and clearance in the machine.
  • Shorter tools are usually the better call when extra reach isn't needed. They run more rigidly and with less vibration.

Storm XL 3100 Series – Extended Length Sizes

The Storm XL 3100 series handles situations where the standard range doesn't reach. These extended-length tools are made for deeper pockets, taller shoulders, and part geometries that require more cutter length without switching to a different tool family.

A few things worth checking before ordering an XL:
Only go with extended reach if the job actually calls for it.
Look at LOC and OAL side by side; both numbers matter for fit.
Longer tools deflect more under load, so setup rigidity becomes a real factor.
Match the cutter length to what the part geometry actually needs, not to what feels like a safe buffer.

Eccentric Relief: The Storm Advantage

HD eccentric relief is one of those design choices that makes a real difference in hard-material applications. Unlike hollow-ground relief, eccentric relief puts more material directly behind the cutting edge, which gives it better support under radial load and resistance to chipping.

For machinists reviewing eccentric relief end mill sizes, it's worth remembering that diameter is only part of the picture. Length, coating, holder type, and workpiece material all shape how the tool holds up through a full run.

What eccentric relief brings to the cut:
Stronger edge support behind the cutting line.
Less chipping under heavy radial pressure.
More consistent performance in long machining cycles.
Better wear behavior in alloys that generate high cutting temperatures.

Coating Options

Storm tools ship with a bright finish as the standard option. AlTiN coating can be added by appending "AlTiN" to the part number at ordering. Other coatings may be available depending on material and job requirements; it's worth asking directly.

Coating choice affects more than tool life. It changes how heat is managed, how the edge holds up in the specific alloy being cut, and how fast the tool can run before performance drops off. For titanium milling carbide specs, passing along the material grade and cutting conditions when requesting a recommendation will get a more useful answer than asking in general terms.

Custom Sizes and Special Requests

Standard charts cover the majority of work, but they don't cover everything. Special sizes, lengths, radii, and coating combinations are available through CGS Tool's custom tooling process. When a standard cutter would require compromising on geometry or reach, a custom order makes more sense than working around a tool that wasn't built for the job.

To get a useful response on a custom request, include:

  • Required diameter.
  • Shank size.
  • Length of cut.
  • Overall length.
  • Corner radius requirement (if applicable).
  • Coating preference.
  • Work material.
  • Type of milling operation.
  • Quantity needed.

The more specific the details, the faster the review moves.

Frequently Asked Questions

What is the largest diameter available in the Storm 3000 series?
The largest standard size is EDP 3033, with a 1-inch diameter, 1-inch shank, 1-1/2 inch LOC, and 4-inch OAL. Larger custom sizes may be available upon request.

What is the longest length available in the Storm XL 3100 series?
EDP 3136 is the longest listed option, with a 1-inch diameter, a 4-inch LOC, and a 6-1/2 inch OAL. It's built for deep-reach applications where standard lengths fall short.

Can I get the Storm end mill with a corner radius?
Yes, corner radius options are available for edge strength on demanding cuts. Special radii beyond the listed options can also be requested through the CGS Tool directly.

What tolerances do Storm 3000 series end mills hold?
Cutting diameter runs +.000 / -.002 inch, and shank diameter holds +.000 / -.0005 inch. These tolerances support a reliable fit across most standard holders and collets.

How do I request a custom size or length for the Storm series?
Submit the diameter, shank, LOC, OAL, radius, coating, material, and operation type to CGS Tool. Complete job details help move the review along without back-and-forth.
