Indexable WC Insert U Drill for Shallow Hole

RONGKE is a China manufacturer offering the Indexable WC Insert U Drill for Shallow Hole for buyers who need to confirm WCMT replacement stock and blind-hole bottom allowance. The WC-series U drill uses separate center and peripheral inserts to produce shallow holes. Its WC insert seats distinguish this body from the SP series, so the body code and WC insert size are the starting points for replacement orders.

How the Assembly Works

WCMT inserts occupy the center and outer seats of the WC body. Keep the two cutting positions identified when checking wear or ordering replacement components.

Key Facts at a Glance

Four Checks Before Ordering

Identify the WC pocket and insert size

Use WCMT03, 04, 05, 06 or 08 as specified by the WC body code. A matching nominal hole diameter does not make an SP insert compatible.

Allow for the WC blind-hole bottom

The catalog lists a bottom wave height of 0.50–1.25 mm across the WCMT sizes. Include the appropriate allowance if a subsequent operation needs a flat bottom.

Select the shortest WC depth series

Compare the 2D, 3D, 4D and 5D WC tables with actual usable depth. For the Ø20 mm 2D example, effective length is 40 mm.

Separate center and peripheral replacement needs

Record which cutting position is worn and the full insert code before ordering spares. Inspect the associated seat and fastening screw when replacing an insert.

Application Fit

Choose the Indexable WC Insert U Drill for Shallow Hole when the job calls for WCMT replacement stock and blind-hole bottom allowance. Use the WC configuration for shallow holes where WCMT replacement stock and the listed blind-hole bottom allowance suit the process. Select the required WC length and keep the center and peripheral pocket references available for repeat orders.

Selection guide — WC vs SP: WC uses WCMT pockets and lists a 0.50–1.25 mm bottom wave; SP uses SPMG pockets and lists 0.30–0.90 mm. Choose the pocket system first, then the depth series. Neither bottom-profile table establishes a flat-bottom finish.

FAQ

1. Q: Can WC and SP inserts be interchanged?

A: No. WCMT and SPMG require their matching WC and SP pockets; equal hole diameter is not evidence of interchangeability.

2. Q: Does a WC U drill leave a flat blind-hole bottom?

A: No. The WC table specifies an insert-dependent bottom wave of 0.50–1.25 mm. Allow for finishing if a flat bottom is required.

3. Q: How do I choose between the WC length series?

A: Select a listed 2D–5D WC body whose effective length reaches the feature. Overall length includes the machine-side portion.

4. Q: Must both cutting positions use an unverified substitute?

A: No. Identify each worn position and order the specified WC insert and fastener; do not substitute an unverified part.

Inspection and Supply Details

Production & inspection

For this order, inspection should address WC pocket identification, center/peripheral seating and cutting-edge runout on the assembled body. Add the required tolerances to the purchase drawing before agreeing an acceptance record.
