Why Choose Our Reaming Tools?
Our carbide reamers are used for finishing holes with superior dimensional accuracy of H7 and H8 tolerances.

UMG Carbide Substrate
Our reaming tools are manufactured from 0.2μm ultra-fine grain carbide with a uniform grain structure and excellent density.

Multi-Land Margin Design
4 to 8 guide margins are typically distributed along the sizing section of the reaming tool body.

Cutting Edge Preparation
All the cutting edges of reaming tools are specialized with the controlled edge radius typically ranging from 5–15μm.

Optimized Flute Geometry
Designed with precisely-ground flutes, our carbide reamers can achieve efficient hole reaming with specialized helix and flute dimensions.

Unequal Pitch Design
Our reamers are designed with unequal pitch, and variable flute spacing delivers uneven tooth arrangement.

Unique Chamfer Design
Versatile chamfer angles and lead lengths are available to suit machining different workpiece materials with different hole tolerances.
Reaming Tool Geometry Breakdown
1.UMG Carbide Substrate
The 0.2μm ultra-fine grain carbide substrates can deliver higher transverse rupture strength and superior durability, enabling edge stability with minimal edge chipping.
2.Multi-Land Margin Design
Precisely ground multi-land margins offer radial guidance, enhancing hole straightness and cylindricity with sizing stability.
3.Cutting Edge Preparation
Micro-honed cutting edges with 5 to 15 μm edge radius can minimize grinding defects and micro-chipping, improving edge strength and wear resistance.
4.Optimized Flute Geometry
The flutes are optimized with engineered flute profiles and sufficient chip space to promote the chip flow and torsional stiffness.
5.Unequal Pitch Design
In reaming applications, unequal pitch design will disrupt harmonic vibration frequencies, greatly decreasing the tool chatter and enhancing hole roundness.
6.Unique Chamfer Design
Precision-ground lead chamfer features optimized chamfer angles, enabling gradual stock removal and decreased cutting impact to enhance dimensional consistency.

German machinery is the strong manufacturing foundation of JINOO. We have introduced the professional production ecosystem to manufacture high-quality reaming tools. Advanced 5-axis CNC grinding machines can boost high-volume manufacturing with tight tolerances.


Advanced Quality Inspection System
1. ZOLLER G3 Tool Measurement: Applied for the comprehensive verification of the reamer geometry, dimensional consistency, and flute symmetry with measurement tolerances within ±2 μm.
2. PG1000 Optical Inspection: Utilized for the microscopic optical inspection of cutting edges and coating conditions of reaming tools to avoid potential defects.
3. Parlec Tool Presetting: Used for inspecting the final tool assembly and machine-side simulation to ensure reamer length accuracy and controlled runout values.
We have formed a professional quality inspection system to ensure 100% quality verification of our reaming tools. In addition, JINOO has employed the ERP system to monitor every manufacturing stage.
Fine-grain Carbide Tool Material
- We source fine-grain carbide tool material from well-renowned raw material suppliers like GESAC, Kennametal, Sandvik, Gühring, and CB Ceratizit.
- Featuring high-hardness carbide substrates, our reaming tools can last longer than standard reamers with excellent durability and wear resistance.
JINOO can ensure you 10% to 12% cobalt content in our tungsten carbide.


Virgin Carbide Instead of Recycled Carbide
JINOO’s Virgin Carbide used in our reaming tools:
- Higher consistency
- Superior rigidity
- Fine grains
- Uniform cobalt distribution
- No impurities
- Dense structure
Competitor’s Inferior Recycled Carbide:
- Unstable tool rigidity
- Lower wear resistance.
- Many impurities

FAQ about Reaming Tools
Do you provide customized services of reaming tools?
Of course! We furnish non-standard customization beyond standard sizes according to your personalized needs. Factors such as processing materials, diameter and the choice of coating of JINOO’s carbide reamers can all be modified to meet your exacting requirements. We will provide you with cutting-edge solutions to ensure an exceptional user experience.
What is your MOQ (Minimum Order Quantity) of solid carbide reamers?
If you want JINOO to customize solid carbide reamers for you, there’s generally no minimum order quantity as they are non-standard tools, and even a small order can be accepted.
What payment methods do you accept for reaming tools?
The payment method of our CNC reaming tools can be flexible; we usually accept bank transfer, credit card, and PayPal. If you have other requirements about the payment method, we can modify it based on your order.
For various reaming tools suitable for different application scenarios, clients must identify the most suitable one for specific machining requirements.
- The automotive and aerospace industries
Reaming tools for the automotive industry are expected to achieve tight hole tolerances in machining crankcases, engine blocks, and transfer cases with H6-H7 grade hole accuracy. Our solid carbide reamer has a long lifespan and high reliability in mass production, which is suitable for automobiles of fixed diameter and batch processing.
Internal coolant reamer is more frequently used in manufacturing aerostructure components and engine blocks, especially suitable for deep spiritual machining.
- The die-mold industry
Reaming tools for mold and die require machining deep blind holes and complex hole patterns, enabling higher machining stability with flexibility. Therefore, the spiral and straight reamer is a good choice.
- The energy and automotive sector
The modular and replaceable reamer is suitable for the energy and automotive sector, as it is used for the large-scale machining area, saving time for effective machining.
Carbide reaming tools are important tools used during high-speed reaming, combined with drilling tools to achieve more precise machining.
There are three key ways in which you can use the remaining tools:
- Improve hole accuracy
Enable the improvement of hole accuracy after being drilled to achieve a more precise size with better tolerances.
- Improve the hole’s surface finish
CNC reaming tools, like a reamer, can effectively remove the machining marks left on the hole, enabling the hole wall to achieve a higher roughness grade (e.g., Ra ≤ 0.8μm).
- Fix the hole geometry
This can effectively improve hole roundness and straightness, which are highly used in machining crankshafts and positioning the hole.
You should first use drill bits with smaller diameters to create pre-drilled holes. To achieve optimal surface finish quality, use high-performance solid carbide reamers with proper spindle speeds and feed rates. Remember to use sufficient cutting fluid to promote the chip flow and extend the tool lifespan. Moreover, keep alignment between reamers and the hole axis to prevent tool vibration and oversized holes. Correct reaming techniques can ensure the creation of high-precision holes and excellent hole accuracy.
Carbide reamers and drill bits are different in their function and precision. Drill bits are typically used for drilling initial holes with high material removal rates, while carbide reamers are used for enlarging and smoothing holes to achieve high dimensional accuracy. Solid carbide reamers can deliver superior precision and tighter tolerances than conventional twist drills. We recommend you use drill bits with CNC reaming tools for high-accuracy hole machining to optimize surface finish quality.
Solid carbide reamers are designed with several flutes to remove a small amount of material from the pre-drilled hole surfaces. Compared with drill bits, carbide reamers focus on precision machining with minimal material removal. Straight or helical flutes can promote smooth chip evacuation with superior hole roundness. Solid carbide reamers are extensively used for hole finishing in aluminum and steel parts.
