Sutton 3mm D364 90° Carbide Spotting Drill Bit - VHM
Available
The Sutton D364 is a solid carbide spotting drill with a 90° Form A point and an AlCrN coating. The drill diameter (d1) is h6 and the shank is h9, and the drill is made to approximately DIN 1897.
Precision drill for machine use; rigid design for "seat" position accuracy; 90° offers hole chamfering and spotting with the one tool; only drill to the depth of the point.
This is the metric range: 9 sizes from 3 to 20 mm, with flute lengths of 9 to 35 mm and overall lengths of 46 to 131 mm.
Where this product is used
- Spotting holes before drilling, with the drill used only to the depth of its point. The 90° point also chamfers the hole in the same operation.
- Materials rated Optimal for this drill: non-alloy steels; low-alloy steels; high-alloy and tool steels; ferritic and martensitic stainless steels; austenitic stainless steel; duplex stainless steel; and precipitation-hardening stainless steel.
- Also rated Effective: Fe-based high-temperature alloys; Ni / Co based high-temperature alloys; titanium and titanium alloys; and chilled and hardened cast iron.
- Rated Optimal for some grades and Effective for others: grey cast iron; nodular cast iron; malleable cast iron; and hardened steel (45 to 62 HRC).
Finish
Aluminium chromium nitride (AlCrN). AlCrN has a microhardness of 3200 HV and thermal stability up to about 1100 °C (2012 °F), and is used for low-alloy and high-tensile steels, hardened steels up to 54 HRC, high-speed machining and use with minimum quantity lubrication (MQL) and dry machining.
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
- Only drill to the depth of the point.
- 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).
Accuracy
The drill diameter (d1) tolerance is h6 and the shank tolerance is h9.
