WVT R12 Drill Bodies

Reusable drill bodies for replaceable WVT carbide heads in the 12×D depth group. The listed models cover head diameters of 11.00–52.99 mm and shank diameters of 16–50 mm.

Select the body by its head-diameter range and seat size, then match the head geometry, grade and fastening components to the application.

Overview

Body and head selection

WVT R12 is the 12×D drill-body group within the WVT replaceable-head drilling system. Select the required cutting diameter within the body model’s listed D1 interval, then verify the matching seat size and screw version.

Head diameter: use D1 min–max; shank diameter D is not the cutting diameter.
Assembly: match both the head diameter and seat family before selecting the fastening components.
Machine fit: check overall length, projection, shank length and available clearance for the chosen model.

Dimension guide

Symbol	Meaning
L	Overall length shown in the drawing
LC	Fluted length shown in the drawing
L1	Length from the head end to the shoulder
L2	Front axial dimension shown in the drawing
LS	Shank length
D	Shank diameter
D1 min / max	Compatible head-diameter interval

Enquiry checklist

Provide the body model, head diameter, hole depth, workpiece grade and hardness, machine interface, coolant capability and quantity.

Application Data

Depth group: 12×D. Cutting conditions must be selected for the actual head geometry, grade, workpiece and coolant arrangement.

PG head cutting conditions

Internal coolant · metric. The table below contains PG head reference data. It is not a universal recommendation for all heads used with R12 bodies. P1–P6 and K1–K6 identify material subgroups; confirm the exact workpiece subgroup before use.

For PG heads drilling deeper than 7×D, centring is recommended before drilling.

Accessories

Match the screw to the selected body model and installed interface version. An M3 revision is recorded for the 18.01–19.99 mm group; confirm the assembly version before substituting a screw.
