Direct Factory Sales & Custom Manufacturing
Carbide drills, end mills and reamers, built around your material, part geometry and machining requirements.
KY TOOLS · Changzhou, China
We manufacture carbide cutting tools for drilling, milling and hole finishing, with a focus on internal-coolant drills and custom geometries. Start with a standard tool family or bring us a feature that needs a dedicated solution.
Our manufacturing workflow connects application review, CNC grinding, edge preparation and dimensional inspection. Tool geometry and acceptance requirements are defined around the job you need to machine.

See the grinding, finishing and measurement stations in our workshop—and the role each plays in turning a tool specification into a finished cutting tool.
01 / CNC tool grinding
Our Walter CNC grinding equipment produces cutting geometries for carbide tooling. The tool drawing defines the profile, flute form and working dimensions to be produced, including the relationships needed for custom cutting tools.

02 / Tool production
ANCA grinding equipment supports our tool-production workflow. Grinding setup and geometry are reviewed against the tool specification, with the approved dimensions providing the reference for repeat orders.

03 / Dimensional inspection
Optical measurement supports checks of tool dimensions and geometry. Mark critical diameters, radii and profile requirements on your drawing, and include any inspection-report requirements with the inquiry.

04 / Finishing
Our finishing work area supports groove polishing and edge preparation. These operations are reviewed with the intended cutting geometry and workpiece application, rather than applying one edge treatment to every tool.
Explore the finishing station →Solid carbide, internal-coolant, step and modular drills. Choose by hole diameter, depth, entry condition and coolant delivery.
Learn more →Square, ball nose and corner radius end mills, with material-specific ranges for steel, stainless steel, aluminum and more.
Learn more →Straight-flute, spiral-flute and coolant-fed reamers for prepared holes. Define the final size, tolerance and finishing allowance.

Explore specialized cutting materials and geometries for your next application.
Explore cubic boron nitride tools for finishing hardened ferrous parts. Compare flat-bottom, curved-surface and corner-radius profiles for your part geometry.
Compare polycrystalline diamond tools for non-ferrous and abrasive workpieces, including dovetail, form, chamfer, slot and single-edge cutters.
Explore solid ceramic and cermet cutter categories for composite trimming, profiling and edge finishing. Review the cutter material alongside the laminate and machining process.
Explore drawing-based cutters for profiles, difficult access, special operations and production improvement. Start with the finished feature and its tolerance.
A clear path to production
Send the workpiece grade, drawing, machining operation and current tool setup. Highlight access constraints and the surfaces that matter.
Review the profile, cutting length, neck clearance and shank. Agree on the drawing and the critical dimensions before ordering.
Specify dimensional checks, reporting and any sample evaluation needed for a new geometry or application.
List quantities by size and confirm the delivery destination. Keep the agreed tool revision as the reference for repeat purchases.
