HSS Morse Taper Shank Drill Bits

A conventional cylindrical-shank drill relies on a chuck or holder to grip the tool. A Morse taper shank drill, by contrast, is designed to seat in a matching tapered socket. The connection between the drill and the machine therefore needs to be confirmed before the cutting specification is finalized.

For procurement, it is important to check three things together:

Drill diameter + Morse taper + machine interface

For example, ordering a 20 mm HSS Morse Taper Shank Drill Bits without confirming whether the machine accepts the required MT2 connection can leave the cutting diameter correct but the tool unusable on the intended machine.

Key Facts at a Glance

Technical Specifications

Common reference sizes in mm. Final material, geometry, dimensions and availability are confirmed with the quotation.

A Drill Built Around the Machine Connection

The value of HSS Morse Taper Shank Drill Bits lie in how the complete tool fits into the machining setup.

Morse Taper Shank

The tapered shank is made to seat against a corresponding Morse taper socket. Correct matching and clean mating surfaces are essential for proper installation.

HSS Cutting Body

The cutting portion uses high speed steel for conventional metal drilling applications. The reference design is supplied with an uncoated cutting section.

118° Point

The 118° point provides a conventional cutting geometry for the listed drilling configuration and can be specified together with the required diameter and taper.

DIN 345 Configuration

DIN 345 provides a recognized dimensional reference for Morse taper shank twist drills, giving buyers a clearer basis for comparing sizes and machine compatibility.

Get the Taper Fit Right

Before putting HSS Morse Taper Shank Drill Bits into production, the connection itself deserves attention.

The MT number should be checked against the machine spindle or sleeve. The taper surfaces should be clean before assembly so that debris does not interfere with seating. For larger diameters, machine capacity, available travel and torque should also be considered rather than selecting the drill by diameter alone.

The workpiece matters as well. Material grade and hardness affect the cutting conditions, while hole depth determines the required working length.

If a sleeve or adapter sits between the machine and drill, its specifications should be included in the tooling enquiry so that the complete setup can be reviewed.

RONGKE: Standard Tools with Application Support

RONGKE has in-house capabilities covering R&D, production and inspection of precision hole-processing cutting tools, supported by an independent laboratory and more than ten years of manufacturing experience in this field. The company supplies standard tooling as well as non-standard cutting tools, with engineers available to review machine conditions, workpiece requirements and sample trial cutting when needed. This allows buyers to confirm not only the drill specification but also whether the selected configuration fits the intended machining setup.

Before You Request a Quotation

To identify the correct Morse taper drill, send RONGKE the following information:

● Drill diameter

● Required Morse taper

● Hole depth

● Workpiece material and hardness

● Machine type

● Spindle or sleeve specification

● Adapter requirement, if applicable

● Required quantity

For repeat purchasing, providing the existing drill specification or machine interface can also help reduce unnecessary back-and-forth during quotation.

FAQ

What does the MT number mean on a Morse taper drill?

The MT number identifies the Morse taper size of the shank. It needs to correspond with the taper socket or sleeve used by the machine.

How do I know whether I need MT1, MT2 or MT3?

Check the Morse taper specification of the machine spindle, sleeve or adapter first. The appropriate drill should have the corresponding taper connection.

Can a Morse taper drill be installed in a normal three-jaw chuck?

It is not intended to be used like a standard cylindrical-shank drill. A suitable holder, chuck or taper adapter should be selected according to the machine arrangement.

Are the adapter and sleeve supplied with the drill?

The reference product is the drill itself. If a sleeve or adapter is required, include it separately in the enquiry so the supply configuration can be confirmed.

What machines are suitable for these drills?

The reference applications include compatible drill presses, radial drilling machines and lathe tailstocks. The machine's taper, capacity, travel and torque should be checked for the selected drill size.

What diameter range is available in the reference configuration?

The listed reference sizes range from 14.0 mm to 28.0 mm, with MT1, MT2 and MT3 configurations depending on the diameter.

Can RONGKE supply a different taper or non-standard specification?

RONGKE develops both standard and non-standard hole-processing cutting tools. For a special requirement, provide the required diameter, taper, length, workpiece and machine information for technical evaluation.

What information is needed for a quotation?

Please provide the diameter, MT number, hole depth, workpiece grade and hardness, machine type and quantity. If an adapter or special configuration is required, include those details as well.
