Modular Drill Body Selection and Compatibility | Ruilif
Release Time:
Sep 14,2026
Choose a Ruilif modular drill body by compatible head, usable depth, holder interface and coolant arrangement. See the details needed for a replacement-body enquiry.
Modular Drill Body Selection and Compatibility
The reusable part of the drilling assembly
A modular drill body carries the cutting component and transfers load from the holder to the cutting zone. Its condition and installation affect the complete assembly. When replacing a body, use the model designation and interface details; nominal hole diameter by itself is not a sufficient ordering reference.
Head compatibility comes first
Confirm the product family, body designation, approved head sizes and locking parts. A head that appears to fit may still have a different locating surface or locking arrangement. Supply photographs of the existing markings and connection when identification is uncertain. Do not modify a locating seat or substitute locking hardware to force a match.
Distinguish usable depth from overall length
The catalog includes MD bodies identified as 1.5-times-diameter and 3-times-diameter versions. These designations help distinguish depth options, but actual usable reach must be checked against the selected model and installation. Allow for the holder, clamping length, entry clearance and any required breakthrough. Avoid selecting extra overhang merely because a longer body is available.
Review holder and coolant connections
Provide the machine spindle and holder interface, the available clamping space, and whether coolant is supplied through the tool. Check that the assembled coolant path is unobstructed. Required pressure and flow depend on the tool and application; there is no universal setting that can be inferred from the body diameter alone.
Inspect before reusing the body
Clean the locating surfaces and inspect them for damage, fretting or contamination. Check locking parts and the cutting-component seat against the supplier instructions. If a crash, repeated loosening or an unexplained change in hole size has occurred, investigate the body and holder before installing another cutting head. Replacing a consumable does not repair a damaged interface.
Replacement-body enquiry checklist
Include the body model, required head diameter, working depth, shank or holder interface, workpiece material and machine type. State whether the request is for a bare body or an assembly with a head and locking parts. This distinction helps avoid ordering an incomplete or incompatible replacement.
Does a longer body give the same result?
Not necessarily. Changing reach changes the setup and may require a different operating window. Confirm the shortest suitable reach with the supplier, then validate the selected assembly under the intended workholding and cutting conditions.
