Compare Product Types

Use the hole requirement first, then compare tool construction, depth ratio, coolant delivery and the dimensions available for each product type.

Depth-ratio labels and catalog dimensions help identify a suitable product type. They do not guarantee hole tolerance, surface finish, tool life, cutting parameters, machine compatibility or current stock.

Review Application Inputs

Choose Holemaking Tools for Your Application

Prepare the complete hole geometry, workpiece and setup information before requesting product selection support.

  • Operation: drilling, pilot drilling, deep-hole drilling, replaceable-head drilling or reaming.
  • Hole type: through, blind, stepped or another stated geometry, including entry and exit conditions.
  • Required hole diameter, depth, depth-to-diameter ratio and any pre-hole or stock allowance.
  • Hole tolerance, surface requirement and inspection method when these are controlled features.
  • Workpiece material, grade, hardness and stock condition when known.
  • Machine, spindle interface, holder, overhang, runout and rigidity information when available.
  • External, internal or other coolant delivery, including coolant pressure and filtration when known.
  • Current tool or drawing, cutting conditions, observed issue, quantity, destination country and target date.

Tool selection depends on the complete hole geometry and setup. A diameter or depth-ratio label alone is not enough to confirm tolerance, surface finish, cutting conditions or tool life.

For a new drill geometry or a requirement outside the current range, use Custom Cutting Tools to submit the part and tool drawings for feasibility review. Review does not guarantee that every requested geometry, material, tolerance or coating can be manufactured.

Send the complete hole and setup requirements so the appropriate product type can be reviewed.

Holemaking Tools are manufactured by MSU. The available range covers five drilling and reaming product types with model-specific dimensions and application requirements.

See the MSU Factory page for manufacturing facilities and Quality Control for inspection processes. Product dimensions, inspection requirements and acceptance conditions are confirmed using the selected model, order details or approved custom drawing.

Factory photos and equipment information describe MSU’s manufacturing and inspection environment. Hole tolerance, surface finish, tool life and machining results depend on the selected product, workpiece and operating conditions.

Review the inspection process used to confirm product and order requirements.

Holemaking Tool Selection Questions

Which product types are included in Holemaking Tools?

The range includes Micro Drills, Solid Carbide Drills, Solid Carbide Deep Hole Drills, Replaceable Head Drills and Solid Carbide Reamers.

Are shallow-hole drilling inserts part of Holemaking Tools?

No. SPMG and WCMX inserts are covered on the separate Shallow Hole Drilling Inserts page under Carbide Inserts.

How do I choose between standard and deep-hole solid carbide drills?

Start with the required diameter and depth-to-diameter ratio. Solid Carbide Drills cover the available 3D, 5D and 8D groups, while Solid Carbide Deep Hole Drills cover the available 10D–30D groups. The complete setup still requires review.

Does a catalog depth ratio guarantee a drilling result?

No. It identifies a product group. Workpiece, machine, holder, coolant, runout, hole geometry and cutting conditions also affect the application.

Can MSU review a custom holemaking tool?

Yes. Submit the part and tool drawings and application conditions for feasibility review. Review does not guarantee every requested geometry, material, tolerance or coating.

Does the catalog show current inventory?

No. Catalog availability information is not live stock data. Current availability is confirmed in the quotation.

What is the order-completion period?

Completion of the whole order is guaranteed within 25–30 days from order placement.
