CORE PRODUCT FAMILIES

Four Tool Families for Precision Holemaking

Choose by the operation the hole needs — drilling, deep drilling or bore finishing — and by whether the workpiece is non-ferrous or ferrous. Each family carries its own selection criteria and inspection points.

MANUFACTURING & QUALITY

Built In-House. Documented Before Release.

Grinding, erosion, measurement and release stay with one team — no third-party handoff between stages.

Grinding and erosion platforms — EWAG, WENDT and VOLLMER platforms cut PCD and carbide edges to the approved tool design.
Three defined inspection points — Tool geometry, assembled runout and machined-part acceptance, measured on ZOLLER equipment.
ISO 9001:2015, certificate on file — ZGTC22Q01715R0, valid through 2028-10-23; runout ≤0.002 mm where specified.

Manufacturing & Quality Evidence

CHOOSE BY APPLICATION

Tooling Solutions for Critical Components

Start with the component and the machining challenge. Each route connects the workpiece, material and recommended tool platform.

Automotive Manufacturing — Cylinder heads, transmission housings, valve bodies. PCD reamers and custom tools.
EV Components — Motor housings, battery-system parts and precision aluminum bores. PCD reamers and multi-step tools.
Compressor Components — Scroll plates, housings and bores that need stable geometry. PCD form tools and reamers.
General Engineering — Steel, stainless steel and mixed-volume precision holemaking. Solid carbide drills.
Something else — Send the part drawing; the route is defined from the bore, tolerance and machine.

Aluminum EV motor housing with precision bores and a large sealing face — Bores, sealing faces and mounting holes finished in one setup.

CHOOSE BY MATERIAL

Match the Tool to Workpiece Behavior

Material controls heat, chip formation, edge wear and surface response. Start with the grade, then match geometry, tool material and coolant.

Aluminum Alloys — Surface finish and chip control. PCD reamers for housings and valve bodies.
High-Silicon Aluminum — Wear control and hole consistency in abrasive cast alloys. PCD reamers.
Steel — Heat control and chip evacuation in carbon and alloy grades. Solid carbide drills.
Stainless Steel — Work hardening and thermal control. Solid carbide drills with matched edge preparation.
Grade not listed — Send the grade, hardness, hole drawing and machine conditions for review.

CUSTOM TOOL ENGINEERING

From Drawing Review to Production-Ready Tool

Custom tooling runs as an engineering workflow — each stage fixes the inputs, decisions and deliverable.

01 Drawing & Application Review — Part drawing, material, tolerance, hole condition, machine setup and coolant.
02 Tool Concept & Quotation — Tool structure, cutting geometry, guidance, coolant route and interface.
03 Engineering & Manufacturing — Production drawings, tool body, cutting material and edge process.
04 Precision Inspection — Critical dimensions, runout, cutting-edge condition and defined inspection points.
05 Sample Validation & Repeat Supply — Trial results, wear and hole quality; specification frozen for reorders.

Send Your Drawing Discuss Your Application

REAL APPLICATION CASES

Real Applications. Documented Engineering Decisions.

Anonymized customer case, structured around the machining problem, the tool strategy and the validation checkpoints.

Custom PCD combination drill-reamer for a 6061 aluminum brake valve body

01 Machining problem — Separate operations added tool changes and alignment risk between drilling and finishing.
02 Tool strategy — One custom PCD combination tool integrated the features around the drawing and machine interface.
03 Shop-floor outcome — Fewer tool changes, with validation focused on hole quality and repeatability.
Validation checkpoints — Hole size, surface finish, tool wear, cycle stability.
