Sutton 30.0mm MT3 HSS Taper Shank Drill Bit
Part No: D1153000 | Barcode: 9311963006031 | Series: D115 Morse Taper Shank
The Sutton D1153000 is a 30.0mm Morse taper shank drill, MT3 taper, designed for direct mounting in lathe tailstocks, drill press spindles, and milling machines. The self-locking Morse taper transmits torque without needing a chuck, so larger holes go in straighter, with no slip and no chuck-jaw deflection.

Key Features & Benefits
- Self-locking MT3 Morse taper — the precision-ground tapered shank wedges directly into a matching tailstock or quill socket, transmitting torque without slipping and without the deflection of chuck jaws. Ejected with a Morse taper drift, ready for the next size.
- M2 high-speed steel — standard tool steel for general engineering work, takes a sharp edge and resharpens easily on a standard drill grinder.
- Steam tempered blue finish — thin oxide layer on the body and flutes that helps cutting fluid wet the surface and reduces built-up edge in mild and free-cutting steels.
- 118° standard point geometry — the conventional general-purpose point. Forgiving in soft and medium steels; resharpens easily; works with any standard drill grinding fixture.
- DIN 345 / ISO 235 dimensions — flute and overall length cut to the international standard, so any DIN-compliant tailstock or sleeve socket fits exactly.
- 5xD maximum cut depth — the flute length supports holes up to 5x the drill diameter without resorting to a special-length drill or peck cycle.
When to Use This Drill
The Sutton D1153000 (30.0mm MT3) is the right choice when running larger drills in machine tools — lathe tailstock drilling for facing operations, drill press work over 13mm where chuck capacity runs out, or production drilling on a mill where the taper shank stays mounted between jobs. For hand-held drilling or use in standard 3-jaw chucks, choose a parallel-shank D101 jobber or D188 reduced-shank drill instead.
Pro Tip: Match the MT3 taper exactly to the machine’s socket — if your tailstock is MT2 and you need to fit an MT3 drill, use a Morse taper sleeve adapter (sold separately). Don’t force a smaller taper into a bigger socket; it won’t self-lock and the drill can spin in the socket and chew up both the drill shank and the socket. Wipe both faces clean before mounting; even fine swarf on the taper face will throw the centring out by tens of microns.
