WHO WE ARE
A Precision Tooling Partner, Not Just a Tool Supplier
HENTRY is the brand of Guangdong Hentry Tool Technology Co., Ltd We focus on application-engineered PCD reamers and precision holemaking tools for high-volume manufacturing.
We work from the customer’s drawing, workpiece material, machine conditions and quality targets to develop tooling solutions that improve bore accuracy, surface finish, tool life and cycle time.
Our primary applications include EV motor housings, transmission components, valve bodies, compressor parts and other precision aluminum components.
Core roles: Jiack Liu — Engineering Director (application review, tool concept, inspection scope). Kevin Zeng — Operations Director (RFQ coordination, project continuity, distributor/OEM communication).
WHAT WE ENGINEER
Application Engineering Capabilities
Custom Tool Design
PCD grade, cutting-edge geometry, guide structure, coolant channels and multi-step features are configured around the machining application.
Precision Manufacturing
Critical geometry, runout, cutting edges and tool interfaces are controlled through defined manufacturing and inspection processes.
Process Validation
Trial results are evaluated against dimensional stability, surface finish, tool life, cycle time and cost per component.

APPLICATION EXAMPLES
Published Application Notes (Anonymized)
Examples below reuse engineering logic already published on HENTRY product and resource pages. They are process notes—not customer names, ROI claims or guaranteed tool-life figures.
Aluminum housing threads — milling vs tapping
On aluminum housings and manifold ports, tap-drill size and drilled depth often decide whether a blind-hole tap has room to finish the thread. Thread milling is commonly the safer route for blind holes close to the bottom, thin walls and threads that need size compensation; tapping remains faster for many high-volume through holes. For high-silicon aluminum, a PCD thread mill may be evaluated.
Read the thread milling vs tapping guide · Solid carbide thread mills
Hardened-steel drilling — start from measured hardness
Undefined “hardened” on an RFQ is not a tool SKU. HENTRY frames solid carbide drilling from the hardness measured where the drill will cut (with scale stated), how the part was heat-treated, and machine/holder rigidity. The hardened-steel series covers an HRC 45–65 application window; fit is confirmed from your reading and setup—not from a generic blog chart.
MANUFACTURING & INSPECTION
Production Capability You Can See
HENTRY combines CNC tool grinding, laser processing and tool inspection to support drawing-based PCD and carbide tooling projects. Final process and inspection requirements are defined for each tool design.
Planning a custom tool?Send the drawing, material, machine conditions and quality target for an application review.
Start an Application ReviewFROM TOOL INSPECTION TO PART VALIDATION
Define What Must Be Measured
Agree on the inspection scope before manufacture. Equipment photographs show a process context; they do not establish an achieved tolerance or surface finish.
Tool Geometry
Define cutting diameters, step lengths, shank or interface dimensions and the features to be checked against the approved drawing.
Assembled Runout
Specify the reference axis, holder, clamping condition and measuring position. Runout measured on a tool is not the same as a finished-hole diameter tolerance.
Machined-Part Acceptance
Validate hole size, roundness, cylindricity and surface finish on sample components. Record the material, machine setup, coolant, cutting data and agreed tool-life endpoint.
NEXT STEP — CORE TOOLS & RFQ
Specify the finished hole / face requirement, then choose the conversion path:
Request the inspection documents required for your project during quotation. Report availability and sampling requirements must be agreed before order confirmation.
