For shorter holes and accessible tip replacement, RONGKE Quick Change Self Locking Drill Bits 1.5D 3D supports selection around front access for tip changes in a short-hole setup. Contact us for wholesale enquiries. Their matched TDPA tips are changed from the front with the specified wrench. Request the confirmed body dimensions and tip group so the selected reach suits the hole and replacement access.
RONGKE supplies the Quick Change Self Locking Drill Bits 1.5D 3D as a drilling-tool manufacturer in China. Start the purchase specification with front access for tip changes in a short-hole setup. The 1.5D and 3D self-locking drills cover shorter holes in the quick-change family. Their compact reach suits setups that do not need a longer body, while the front-mounted drill tip can be changed using the matched assembly method.
Configuration Overview
The short TD assembly uses a front-mounted TDPA tip. Check wrench access with the tool installed, particularly where surrounding fixtures restrict the space for a tip change.

Selection Checklist
• Decide between compact 1.5D and 3D bodies
Choose the shortest listed body that reaches the hole. Use the catalog row rather than interpolating: some 1.5D table values require confirmation against the drawing.
• Match the TDPA self-locking tip
The family covers Ø8–32.9 mm. Confirm the diameter group and TDPA locating size so that the radial and axial locking features match the body.
• Check front-wrench access
The self-locking system uses a matched front wrench. Leave access at the cutting end for a tip change and select the wrench group with the body.
• Compare the 3D example with the hole
TD03-200-XP25 lists Ø20–20.90 mm, 63.0 mm effective depth and 147.6 mm overall length. Allow for the actual workpiece entry and holder clearance.

Machining and Setup Considerations
Choose the Quick Change Self Locking Drill Bits 1.5D 3D when the job calls for front access for tip changes in a short-hole setup. The shorter self-locking options address holes that fit the confirmed 1.5D or 3D body dimensions. Their front-change tip arrangement is useful where replacement access can be maintained in the machine setup.
Selection guide — 1.5D vs 3D self-locking: both use the TDPA front-locking system; the distinction is body reach. Use the actual dimensional row, and resolve inconsistent 1.5D table entries before placing a dimensional order.
Quality and Replacement Support
Production & inspection
The relevant acceptance points are short TD body identification, matched TDPA locking fit and front-wrench engagement. These checks should be specified for the selected assembly; request the required records when placing the order.
What to Send Our Factory
For the Quick Change Self Locking Drill Bits 1.5D 3D, send our factory the selected reference, quantity and requirements for front access for tip changes in a short-hole setup. RONGKE can prepare the supplier quotation around that configuration.
FAQ
1. Q: Should I calculate the 1.5D dimensions from its name?
A: No. Use the confirmed dimensional drawing; the 1.5D table contains entries needing clarification.
2. Q: Will a screw-clamped Phoenix tip fit this self-locking body?
A: No. TDPA uses the dedicated self-locking locating arrangement. A Phoenix screw-clamped tip is not an established substitute.
3. Q: Must the tool body be removed for every tip change?
A: The catalog describes front-wrench tip changes without removing the body. Confirm access and the matched wrench for the actual setup.
4. Q: What is a concrete 3D size reference?
A: TD03-200-XP25 covers Ø20–20.90 mm, with 63.0 mm effective depth and 147.6 mm overall length.
