Having that leg of the angle iron that you are milling unsupported really isn't the best setup. I'm glad that it worked for you but you should really hold pieces completely.

That formula for calculating spindle speed is wrong too. This is the real formula

(PI * DIA X RPM) / 12 = SFPM

Using your formula it says to run a 5/16 inch cutter at 550 RPM which is only 45 SFPM, less than half the speed you should run. You should mill steel at 100 SFPM or more.

I'll mock up a better setup. Ignore the burn holes in the steel. It is the first piece of scrap angle I found laying around. Anyhow, the hold down on the leg keeps it from fluttering around. Chatter is a bad thing when machining.

  • When performing ‌slot milling, process reliability is extremely important. The chips must be reliably removed from the groove and must not damage the surface. A large number of solid carbide shank cutters and indexable insert side and face mills in various cutting widths and diameters allows a broad range of applications to be covered.
  • High-Speed Steel T-Slot End Mills Use these end mills for general purpose work in most material, such as aluminum, brass, bronze, iron, and steel. They're often used to create slots in machine tool tables, indexing tables, and other workholding surfaces.

The new solid carbide end mill from the GARANT MasterSteel product range offers 5 cutting edges and a new type of knuckle form profile, thereby achieving particularly high performance. The new GARANT MasterSteel SlotMachine from the Hoffmann Group is a solid carbide roughing end mill which achieves high feed rates when slot milling from solid in steel.

The innovative knuckle form profile produces extremely compact swarf. Therefore, the Hoffmann Group was able to construct the milling cutter with five cutting edges. As a result, at a constant feed rate per tooth the new five-edge end mill achieves 25 percent higher process efficiency than a classic four-edge end mill. Thanks to the innovative knuckle form profile, the cutting pressure is lower and higher feed rates can be obtained with a constant load. Due to the compact chips and the lower cutting forces, the new GARANT MasterSteel SlotMachine high-performance end mill is particularly suitable both for milling deep slots from solid and also for machining delicate components.

Before I got a turntable for my mill I needed to mill a through slot (3' radius) in 1/2' thick 6061 plate. I built a turntable with the idea of using a long handle (24') to turn the table after I plunged the end mill through.

Based on its unusual geometry, the new GARANT MasterSteel SlotMachine solid carbide end mill produces chips that are very short, very fine and particularly tightly rolled. These are easily cleared by the flat chip-breaker recesses. The directional chip discharge increases the process reliability, the extremely sturdy core diameter the tool stability.

The GARANT MasterSteel SlotMachine permits plunge angles up to ten degrees. The cutting edge design includes honing to minimise the risk of break-aways. The ultra-fine grain substrate greatly increases the resistance to breakage; whilst the enhanced coating also optimises the wear characteristics and reduces the rate of heat input. The unequal spacing ensures a smooth cutting action.

The new GARANT MasterSteel SlotMachine solid carbide end mill extends the GARANT MasterSteel product range, which currently includes the existing classic four-edge end mills and also the GARANT MasterSteel PickPocket universal end mill plus two solid carbide drills. With these the Hoffmann Group offers state-of-the-art high-performance tools for every application.
