Solberga Model SE725SL | 8-Speed Geared Head | 1.25" Capacity | Power Feed

Solberga Model SE725SL Geared-Head Drill Press

Manufacturer: Solberga (Sweden) | Type: Geared-Head / Production | Swing: 22" – 23"

Professional Overview

The Solberga SE725SL is a heavy-duty, Swedish-built geared-head drill press renowned for its rigidity, precision, and low-maintenance helical gear drive. Unlike belt-driven models, the geared-head design provides constant torque across its entire RPM range, making it ideal for large-diameter drilling, reaming, and tapping in industrial environments. The "SL" designation typically refers to models featuring a Dovetail Way Vertical Column, offering superior stability compared to standard round-column versions.

Technical Specifications

• Drilling Capacity: 1" in Mild Steel / 1.25" in Cast Iron.
• Spindle Taper: #3 Morse Taper (MT3).
• Spindle Speeds (8): Range from 120 to 1,548 RPM (selected via dual levers).
• Quill Travel: 4.5" to 5".
• Spindle to Column Distance: 11.5" (resulting in a 23" swing).
• Motor: 1.8 HP to 2 HP, 2-speed motor (typically 3-phase, 220V/440V).
• Power Feed Rates: Three rates (typically .004, .007, and .011 IPR).
• Weight: Approximately 850 lbs (excluding custom production tables).

Key Performance Features

• Helical Gear Drive: Features fiber-to-steel mesh helical gears for quiet operation and a virtually maintenance-free lifespan. This design eliminates the slipping issues common with V-belts.
• Dovetail Way Column: The SE725SL utilizes a precision-ground dovetail column which ensures the head stays perfectly aligned with the table center even when adjusted for height, a critical feature for high-precision production.
• Integrated Safety: Standard units are equipped with a thermal overload switch, no-volt release, and an emergency stop button.
• Production Versatility: Often mounted on large cast-iron production tables (e.g., 24" x 40"), allowing for heavy workpieces or multi-head "gang drill" configurations.
