Configurations can vary by production revision.
1-1/4-Inch Drilling Capacity
The GHD-20PF is designed for drilling holes up to 1-1/4 inches in diameter, making it suitable for a wide range of professional metalworking applications.
Depending on tooling and operating conditions, the machine can be used with materials such as:
- Mild steel
- Stainless steel
- Aluminum
- Cast iron
- Fabricated metal components
- Structural materials
For larger holes, appropriate pilot-hole procedures, tooling, cutting speeds, and coolant should be used according to the material and tool manufacturer's recommendations.
Power Downfeed
One of the machine's key features is its power downfeed system.
Instead of requiring the operator to continuously control the spindle manually throughout the drilling cycle, the power feed provides a controlled automatic movement of the spindle.
This can help:
- Maintain a consistent feed rate
- Reduce operator fatigue
- Improve repeatability
- Provide smoother drilling of larger holes
- Make repetitive operations more efficient
The operator should select an appropriate feed rate for the material, drill diameter, and cutting conditions.
Geared-Head Transmission
The GHD-20PF uses a geared-head drive system designed for heavy-duty metalworking.
The geared transmission provides direct mechanical power transfer to the spindle and is well suited to applications requiring substantial drilling torque.
Compared with lighter-duty belt-driven drill presses, a geared-head machine is designed with professional metalworking applications in mind.
Heavy-Duty Floor-Standing Design
The GHD-20PF is configured as a floor-standing drill press, providing a stable platform for machining larger workpieces.
Its rigid construction helps minimize movement and vibration during drilling. For best accuracy, workpieces should always be securely clamped and adequately supported.
Multiple Spindle Speeds
The machine provides multiple spindle-speed selections to accommodate different drill diameters and materials.
Using the correct spindle speed is important because cutting requirements change according to:
- Workpiece material
- Drill diameter
- Drill type
- Required hole size
- Cutting fluid
- Feed rate
Always follow the drill manufacturer's recommended cutting parameters.
Manual and Power Feed Control
The power downfeed provides controlled automatic spindle movement, while manual operation can be used when the operator needs more direct control during setup or specialized drilling operations, depending on the machine configuration.
This combination gives the operator flexibility for both repetitive production work and individual machining tasks.
Workpiece Support
A stable work surface is essential when drilling larger holes.
The machine's floor-standing configuration provides a substantial platform for supporting workpieces, while appropriate clamps, vises, or fixtures should be used to prevent movement during operation.
For large or irregular components, additional external support may be required.
Typical Applications
The JET GHD-20PF is suitable for:
- Machine shops
- Metal fabrication
- Industrial maintenance
- Welding shops
- Equipment repair
- Manufacturing
- General machining
- Job-shop operations
- Production drilling
- Structural metalworking
Common Uses
Large-Hole Drilling
Produce holes up to the machine's rated 1-1/4-inch drilling capacity using suitable tooling and cutting parameters.
Repetitive Drilling
The power downfeed makes the machine particularly useful when producing multiple holes with consistent feed characteristics.
Fabrication
Drill mounting holes and other openings in fabricated metal assemblies.
Maintenance and Repair
Prepare replacement parts and repair components for industrial machinery and equipment.
General Machining
Perform routine drilling operations across a broad range of metalworking applications.
Benefits for Professional Users
1-1/4-Inch Drilling Capacity
Provides substantial drilling capability for demanding metalworking applications.
Power Downfeed
Reduces operator effort while providing controlled spindle movement during drilling.
Geared-Head Drive
Provides positive power transmission and is designed for heavy-duty use.
Floor-Standing Configuration
Provides a stable platform for larger workpieces and professional shop applications.
Versatile Speed Selection
Allows spindle speed to be matched to different materials and tooling.
Production-Friendly Operation
The power-feed system is particularly useful for repetitive drilling tasks where consistent feed is important.
Maintenance
Regular maintenance helps preserve drilling accuracy and machine reliability.
- Inspect drill bits and tooling before use.
- Keep tooling sharp and properly installed.
- Check spindle operation and tool retention.
- Inspect the geared-head transmission for abnormal noise or vibration.
- Lubricate the machine according to JET's maintenance recommendations.
- Keep the table and work area free of chips.
- Inspect power-feed components periodically.
- Check electrical components and controls for signs of damage.
- Keep the machine clean and properly lubricated.
- Verify that mounting and structural components remain secure.
- Disconnect electrical power before performing service or maintenance.
Safety Considerations
Always wear appropriate eye protection, hearing protection, safety footwear, and task-specific PPE when operating the drill press.
Secure every workpiece using an appropriate vise, clamp, or fixture. Never hold a workpiece by hand while drilling.
Keep hands, clothing, jewelry, and hair away from rotating tooling and the spindle.
Remove chuck keys and setup tools before starting the machine. Never attempt to change tooling while the spindle is rotating.
Use drill bits and cutting tools appropriate for the material being machined. Select suitable spindle speed, feed rate, and cutting fluid for each operation.
Before making adjustments, changing tooling, or performing maintenance, disconnect the machine from its electrical supply and follow appropriate lockout procedures.
