MD 8xD Modular Drill Body
- Product Description
-

MD 8xD Drill Body for Application-Based Tool Selection
The MD 8xD drill body is part of the Ruilif modular drill system and is used with a compatible replaceable cutting head. The body provides the assembly interface and working reach; it should be specified together with the head and holder, not ordered on depth designation alone.
Compare 7xD and 8xD by the Required Working Length
When comparing depth classes, use the actual dimensions for the selected diameter. Check the distance from the holder to the workpiece entry, the required full-diameter hole depth and the drill-tip allowance. A longer catalogue depth class is not automatically the better choice if a shorter assembly meets the drawing and fixture requirements.
Confirm the Complete Assembly
- Match the drill-body model with the specified cutting-head model and diameter.
- Check the shank and holder connection against the machine setup.
- Identify blind holes, through holes and any angled or interrupted entry surfaces.
- Provide the workpiece material, coolant arrangement and required hole tolerance.
For replacement enquiries, include the markings on the existing body and head. Nominal hole diameter alone is not sufficient to confirm component compatibility.
Request an 8xD Configuration Review
Send the part drawing and current tooling information to Ruilif Tools (Qingdao) Co., Ltd. Confirm the usable depth and operating instructions for the selected assembly before trial machining. No universal speed or feed is specified by the 8xD designation.
Compare the MD 7xD drill body and consult the modular drill body selection guide when checking working reach and assembly compatibility.
