Sutton D103SM3 25 Piece TiNite Jobber Drill Set - HSS
Available
The Sutton D103SM3 is a 25-piece set of D103 TiNite drills in High Speed Steel (HSS), in a ABS plastic case. The set covers 1.0 – 13.0 mm × 0.5 mm steps.
Each drill in the set has 30° right-hand helix flutes (R30), a 118° Form A point, a gold titanium nitride (TiN) coating and is made to DIN 338.
What is in the set
- 25 drills: 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, 10, 10.5, 11, 11.5, 12, 12.5, 13 mm
Drills in this set
Dimensions of each drill in the set, from the individual D103 TiNite items of the same sizes. The 1.5 mm and 5 mm drills use the same DIN 338 lengths as the other D103 sizes of that diameter.

Where this product is used
- General drilling across the materials rated for D103 TiNite drills.
- Materials rated Optimal for the D103: non-alloy steel, about 0.15 %C, annealed; non-alloy steel, about 0.45 %C, annealed; non-alloy steel, about 0.45 %C, quenched and tempered (250 HB); non-alloy steel, about 0.75 %C (annealed and quenched and tempered); low-alloy steel (under 5% alloying elements), annealed; low-alloy steel, quenched and tempered (275 to 350 HB); high-alloy and tool steel; grey cast iron; nodular cast iron; and malleable cast iron.
- General-purpose drilling where a TiN-coated drill is preferred over an uncoated one.
Finish
Titanium nitride (TiN), gold. TiN has a microhardness of 2300 HV and thermal stability to about 600 °C (1112 °F), and is designed to give 3 to 8 times longer tool life than uncoated tools with higher speeds and feeds than uncoated.
Cutting speeds and feeds
Cutting speeds (Vc) and feed numbers are given for the D103. Speed (rpm) = Vc × 1000 ÷ (π × Ø); treat these as starting values.
