Replaceable Blade Deep Hole Spade Drill

RONGKE is a China manufacturer offering the Replaceable Blade Deep Hole Spade Drill for buyers who need to confirm the blade group and the machine-side shank connection. The spade drill uses a replaceable blade mounted at the end of a supporting body. The blade establishes the cutting geometry, while side-lock and Morse-taper body options allow the assembly to be matched to the machine connection.

How the Assembly Works

The blade supplies the spade drill's cutting geometry. The holder establishes reach and the machine connection, so a replacement blade order and a complete-tool order require different component references.

Key Facts at a Glance

Four Checks Before Ordering

Match blade width to the holder group

The blade table spans Ø9.5–114.48 mm across different holder groups. Select the holder code with the blade width; the full range does not fit one holder.

Choose the machine connection

Compare side-lock holders with Morse-taper holders. The machine connection and coolant arrangement are separate choices from the replaceable blade material.

Specify blade material and chipbreaker

Catalog choices include S2 cobalt HSS, S6 powder HSS and G2 carbide, with ST or DT chipbreakers. Match the complete code to the workpiece.

Plan deep-hole entry from the spade guidance

For holes above 8D, the catalog includes a pilot-hole procedure. Review that procedure with the chosen blade geometry rather than assuming direct entry.

Application Fit

Choose the Replaceable Blade Deep Hole Spade Drill when the job calls for the blade group and the machine-side shank connection. The replaceable-blade spade system accommodates varied machine connections through its side-lock and Morse-taper holders. Select blade material and holder group together; deep-hole entry and special bottom profiles require their own review.

Selection guide — Side-lock vs Morse taper: choose the machine connection independently of blade material. The standard spade system offers S2, S6 and G2 blade choices, while a special round or flat-bottom profile needs its own confirmed drawing.

FAQ

1. Q: Can one spade holder accept the entire blade range?

A: No. The Ø9.5–114.48 mm blade coverage spans multiple holder groups and blade thicknesses.

2. Q: Are side-lock and Morse-taper bodies interchangeable at the machine?

A: No. Choose the connection that matches the machine; confirm its specific coolant arrangement as well.

3. Q: Are all catalog spade blades carbide?

A: No. The table also lists S2 cobalt HSS and S6 powder HSS alongside G2 carbide.

4. Q: Does the catalog include guidance for deeper spade drilling?

A: Yes. PDF p.46 includes a pilot-entry procedure for holes above 8D; apply it to the selected blade and setup.

Inspection and Supply Details

Production & inspection

For this order, inspection should address blade thickness, holder-group fit and the selected side-lock or Morse-taper connection. Add the required tolerances to the purchase drawing before agreeing an acceptance record.

Quotation Checklist

For factory supply of the Replaceable Blade Deep Hole Spade Drill, the key purchasing detail is the blade group and the machine-side shank connection. Send RONGKE the component codes so the supplier quotation covers the intended item.
