Replaceable Head Carbide Reamer H7 Tungsten Carbide Modular High Precision Reaming Tool CNC

Short Description:

The Replaceable Head Carbide Reamer is a modular precision cutting tool designed for enlarging and finishing pre-drilled holes to H7 tolerance (±0.01 mm). Its standout feature is the interchangeable tungsten carbide cutting head: when the head wears out, only the head is replaced while the durable shank is reused, cutting long-term tool cost and reducing waste.

Product: Replaceable Head Carbide Reamer
Material: Submicron tungsten carbide

Bullet Points

Modular cost saving ：Only the worn head is replaced; reusable shank cuts overall tooling cost.
H7 high precision ： ±0.01 mm tolerance, H7 hole grade, stable accuracy after head changes.
+40% tool life coating： Dedicated coating extends life up to 40% with lower carbon footprint.
Triple inspection QC ：Triple inspection system ensures drawing-compliant, flawless tools.
Multi-material capability ：Reliable reaming on steel, alloy steel, cast iron, stainless, aluminum & more.
Large/deep hole advantage ： Modular design minimizes tool setting; ideal for large & deep holes.
Full customization： Diameter, tolerance, coating, shank type & grade customizable per drawing.
Inventory & eco win-win：Stock only heads — lower inventory, less waste, faster changeover.

Applications

Automotive：Engine block, cylinder head oil-passage and brake system hole finishing with batch consistency.
Aerospace：High-tolerance components such as turbine blades and landing-gear parts; superalloys & titanium.
Mold & Die：Guide, ejector and insert holes in hardened mold steel (HRC 40–55) targeting Ra 0.4–0.8 μm.
General Machining：Maintenance shops & general CNC work — flexible reaming across steel, aluminum and alloys.
Hydraulics & Energy：Valve bodies, pumps and cylinders with large/deep holes, leveraging fast head swaps and low tool setting.

Hot Q&A

Q1：How often should the reamer head be replaced?
Depends on material and cutting conditions — typically every 500–1,000 holes on hardened steel. Monitor flank wear (approx. 0.1–0.2 mm) and replace before surface quality drops.
Q2：Does one reamer body fit all head sizes?
Yes. The modular standardized interface lets one body support a range of heads. Please check the compatibility chart or contact us to confirm ranges.
Q3：Why choose a replaceable-head over a solid reamer?
Lower long-term cost (head-only replacement), less waste, faster job changeover, smaller inventory (heads only), and reduced downtime.
Q4：Can you customize diameter, tolerance and coating?
Yes. Provide hole tolerance and surface finish requirements; we customize head geometry, coating (TiAlN/AlTiN, etc.) and shank type (HSK/BT/SK/straight).
Q5：What is the MOQ?
Standard sizes: small trial orders (1–5 pcs); custom sizes: 10–20 pcs depending on complexity. Trial orders welcome.
Q6：What is the lead time?
Stock items: 3–7 days; production: 15–25 days; custom/OEM: 25–40 days after design confirmation.
Q7：Do you provide samples?
Yes. Samples available for qualification; sample cost is negotiable and deductible from bulk orders; shipped via DHL/FedEx/UPS.
Q8：What after-sales support do you offer?
Triple inspection before shipment; free replacement for quality issues within 30 days; cutting-parameter and application support; regrinding/recoating services available.
