With HSS drills always use a peck drill cycle; Set your peck depths to a maximum of half your drill diameter ; Example 0.250 inch drill diameter pecking at 0.125 depthsAISI H13 Steel - DIN 1.2344 - JIS SKD61 - Songshun SteelH13 steel is the most representative hot-working tool steel which was used widely. Such as molds for extrusion and metal die-casting molds. It also is called DIN 1.2344 and JIS SKD61 steel. H13 steel round bar sheet plate heat treatment requirements are very strict. The great annealing processing would improve the performance of steel.
The composition of H13 tool steel is shown in Table 1. The electrode of H13 was placed in a 50 kg electroslag crucible furnace to obtain molten steel. The slag in electroslag crucible was a mixture of 60 wt% CaF 2, 20 wt% CaO and 20 wt% Al 2 O 3 to prevent oxidation of molten steel as much as possible during the experiment.

Should be about 70 sfm with HSS. About the only problem that you'll have is tapping, use a good sharp tap. Between the chrome and the moly, it's a little hard on taps and reamers.High-Speed Milling Guidelines for Hardened Tool Steels h13 tool steel sfmMar 01, 2000 · Do not rely on old conventional milling parameters with which you may be familiar. High speeds for milling of tool steels range from about 1,500 to 3,000 sfm. Always consider the actual "sharpness" of your tool. Typical tool edge radius (sharpness) varies between 0.0002" and 0.0004"; therefore, realistic chip loads should be a minimum of 0.0010".
For Tool Diameters 1 8" and Under AD = Dia. of Tool X 0.25 to 0.05. For Diameters above 1 8" AD = Dia. X .05 to 1.5. SFM and Feed For AD between 0.25 to 0.5 of Tool Dia. SFM = 0.8 Lowest Range Value. Feed at Suggested Value. For AD equal and above Tool Dia. SFM = 0.8 X Highest Speed Range.
