MZR/MZL Micro Radius Face Grooving Bar Overview
The MZR/MZL series is a precision-ground solid carbide micro tool designed for radius face grooving in small bores and confined turning features. MZR provides a right-hand cutting configuration, while MZL provides a left-hand configuration. The ground radius cutting profile supports controlled groove transitions, consistent radius formation and stable machining of precision-turned components.
Model Identification Guide
Select the suitable model according to cutting direction, shank diameter, cutting radius, groove width, cutting depth and machining depth.

Key Configuration
Machinable Materials
MZR/MZL solid carbide radius face grooving bars can be applied to precision components made from steel, stainless steel, cast iron and selected non-ferrous materials. Cutting parameters and coating should be matched to the workpiece material and machining conditions.
| Material | Aplicações típicas |
|---|---|
| Aço carbono | Shafts, sleeves and mechanical components requiring controlled-radius grooves. |
| Aço-liga | Wear-resistant precision parts requiring stable groove geometry. |
| Aço inoxidável | Medical, electronic and corrosion-resistant precision components. |
| Ferro fundido | Small housings, sleeves and precision face-groove features. |
| Non-Ferrous Materials | Aluminum, copper and other materials with application-matched geometry. |
Key Product Advantages
Precision-ground radius cutting profiles support controlled groove transitions and repeatable radius dimensions.
MZR and MZL configurations provide flexible selection according to tool approach, spindle direction and holder position.
The compact cutting head provides access to radius face grooves and transitions in confined small-bore features.
Integral solid carbide construction improves rigidity and helps control vibration during precision grooving operations.
Non-standard radius, groove width, cutting depth, machining depth, shank diameter and marking can be customized according to drawings.
Why Choose MZR/MZL Radius Face Grooving Bars
| Recurso | Conventional Tools | MZR/MZL Solution |
|---|---|---|
| Radius Accuracy | General grooving tools may not form a consistent radius transition. | Ground radius profiles support repeatable groove geometry. |
| Tool Orientation | A single cutting direction may limit tool access. | Right-hand MZR and left-hand MZL options provide flexible access. |
| Rigidez | Less rigid tooling may generate vibration in small bores. | Solid carbide construction improves stability and vibration control. |
| Size Range | Standard tooling may offer limited radius and reach options. | Multiple standard radii, groove widths and machining depths are available. |

FAQ & Downloads
Product FAQs
MZR/MZL tools are designed for forming radius face grooves and controlled-radius transitions in small-bore turned components. Typical applications include shafts, sleeves, bushings and other precision parts with confined face-groove features.
MZR indicates a right-hand cutting configuration, while MZL indicates a left-hand configuration. Selection depends on the machine setup, spindle direction, holder position and required tool approach.
The standard MZL range includes R0.5, R0.75, R1.0 and R1.5 mm cutting radii. These correspond to groove widths of 1.0 mm, 1.5 mm, 2.0 mm and 3.0 mm respectively.
Standard MZL shank diameters are Ø4 mm, Ø5 mm and Ø6 mm. The Ø4 mm models have a 15 mm machining depth, while the Ø5 mm and Ø6 mm models have a 22 mm machining depth. The standard overall length is 50 mm.
Typical applications include carbon steel, alloy steel, stainless steel, cast iron and selected non-ferrous materials. Cutting parameters, coating and edge preparation should be matched to the workpiece material.
Selection & Application FAQs
First confirm the required cutting direction and select MZR for right-hand or MZL for left-hand machining. Then select the cutting radius, groove width, cutting depth, machining depth and shank diameter according to the component drawing and tool clearance.
A 1.5 mm groove width corresponds to an R0.75 cutting radius and a 1.6 mm cutting depth. Standard options include Ø4 mm, Ø5 mm and Ø6 mm shanks, depending on the required machining depth and holder size.
The largest radius shown in the standard MZL chart is R1.5 mm. The MZL 6R1.5 L22 T3.0 model has a 3.0 mm groove width, 3.0 mm cutting depth, 22 mm machining depth and Ø6 mm shank.
Minimize tool overhang, confirm the correct center height and cutting direction, control tool runout and verify sufficient clearance. Cutting speed, feed and coolant should be adjusted according to the radius size, workpiece material and machine rigidity.
Ordering & OEM FAQs
Yes. Non-standard radius, groove width, cutting depth, machining depth, shank diameter, cutting direction, coating and edge geometry can be evaluated according to drawings or samples.
Yes. The standard minimum order quantity is 10 pieces. Mixed-model requirements can be reviewed according to the selected cutting direction, radius, shank diameter and available stock.
Please provide the required cutting direction, radius, groove width, machining depth, shank diameter, workpiece material and quantity. A component drawing is recommended for non-standard tools or restricted machining positions.
Yes. Custom model identification, laser logo marking, labels and private-label packaging are available for distributors and tooling suppliers.
In-stock standard models can usually be dispatched within 1–3 working days after order confirmation. Customized tools require separate lead-time confirmation according to geometry, quantity, coating and production requirements.
