Modular Drill - ICD Series Introduction
Created on 2025.12.19
ICD Series Modular Crown Drill Product Introduction
The ICD series modular crown drill is a modular drilling system designed for medium-diameter, high-efficiency, and high-stability drilling operations.
It is suitable for the automotive, construction machinery, general machining, and mass production industries.
The core concept of the ICD series is:
Through a replaceable drill tip design, it effectively reduces the cost per hole while ensuring consistent hole quality.
I. Design Concept of the ICD Series
The ICD series adopts a modular design, mainly composed of the following two parts:
Replaceable Drill Head (ICD Crown Insert / Drill Head)
High-rigidity Drill Body (Steel Drill Body)
When the drill head wears out, only the drill head needs to be replaced to continue machining.
It is not necessary to replace the entire drill bit, nor is it necessary to re-set the tool, significantly reducing downtime.
It is very suitable for mass production and automated production lines.
II. Core Structure and Technical Features
1️⃣ Quick-Change Drill Head
- High-precision positioning structure, high consistency in repeated clamping
- Quick replacement, simple operation
- No need to reset the tool length
- Selectable drill head geometry for different materials
👉 Suitable for multi-shift production and high-upload machining environments.
2️⃣ High-rigidity drill body design
The drill body is made of high-strength alloy steel.
Excellent vibration resistance and stable drilling process.
Stable hole position start-up, less prone to deviation.
Suitable for handling casting surface and intermittent cutting.
3️⃣ Internal Coolant System
Coolant reaches the drill tip cutting zone directly.
Effectively reduces cutting temperature.
Improves chip removal.
Extends the service life of the drill tip and drill body.
4️⃣ Stable Guiding Geometry
Excellent drilling guidance.
Stable hole straightness and roundness.
Ideally suited as a pre-processing step for subsequent finishing.
📐 III. Typical Machining Range
Hole Diameter Range:
Ø8.0 – Ø32.9 mm (Common Range)
Drilling Depth:
3D / 5D / 8D / 10D / 12D
Cooling Method: Internal Coolant
Applicable Materials:
-Carbon Steel
-Alloy Steel
The ICD series Modular Crown drills offer a variety of drilling depths from 3D to 12D within a medium hole diameter range of Ø8.0–32.9 mm, providing flexibility to handle:
General through-hole machining (3D / 5D)
Medium-deep hole machining (8D)
Deep hole and structural component machining (10D / 12D)
Equipped with a high-rigidity tool body and internal cooling design,
it effectively balances drilling efficiency, stability, and tool life in continuous machining and mass production of steel and alloy steel.
