Sutton 3mm D358 Black Magic 5xD Carbide Drill Bit - VHM
Available
The Sutton D358 is a 5 × Ø through-coolant solid carbide drill with a HELICA coating. It has 30° right-hand helix flutes (R30, internal coolant), a 140° 4 facet Form C point and a DIN 6535 HA shank, d2 to h6. It is made to DIN 6537.
Excellent solution for stainless steels and difficult super alloy type materials; optimised geometry ensures no work hardening and high productivity; HELICA for outstanding oxidation resistance and hot hardness. The Black Magic carbide drill ranges target stainless steels and super alloys such as austenitic stainless steels 304 and 316, duplex grades and Inconel 718 and 725 in aerospace and oil and gas work. It has a specially developed edge profile for stainless steel with post-grind treatment of the cutting edges, a 30° helix with an optimised flute core and 'S' type point gash, ultra micro grain solid carbide, and internal coolant to supply the cutting edge and help evacuate chips from the hole.
This is the metric range: 145 sizes from 3 to 20 mm, with flute lengths of 28 to 101 mm and overall lengths of 66 to 153 mm.

Finish
HELICA (AlCrN-based multi-layer). HELICA has a microhardness of 3000 HV and thermal stability up to 1100 °C, and offers superb chip evacuation, improved hole quality, a greater number of regrinds and excellent performance in abrasive material.
Cutting speeds and feeds
Cutting speeds (Vc) and feed numbers for this drill are from the Sutton High Performance catalogue application guide. The table lists the material groups covered. Optimal ratings are shown in bold and Effective ratings in regular type. The rpm and feed columns show what the speed and feed number work out to at Ø6 mm and Ø10 mm (speed in rpm = Vc × 1000 ÷ (π × Ø)). Treat these as starting values and adjust for the machine, set-up and coolant.

Drilling notes
- Step feeding or pecking is required for drilling greater than 3 x Ø.
- When drilling a cast or black (not machined) surface, reduce the drilling speed by 20%.
- For optimal positional accuracy and hole size, the use of spot drills is recommended prior to drilling the desired hole; see Sutton's spotting drill range (D175).
- For hole depths greater than 7 x Ø, pre-drill a pilot hole first for more accurate hole position and to stop the drill wandering. The pilot can be drilled with a short, rigid drill about 3 x Ø deep at reduced feed.
Accuracy
The drill diameter (d1) tolerance is m7 and the shank tolerance is h6.
