Experience unmatched power and precision with the Steelmax D4 PRO, a robust 4-speed magnetic drill purposefully designed for industrial longevity. With an RPM range of 100-500 under load, it’s ideal for both HSS and TCT annular cutters. Lightweight, compact, and portable, this drill features a powerful 1650-watt motor capable of drilling holes up to 4″ (100 mm) in diameter and through 4″ (100 mm) thick material. Optional drill chuck compatibility allows for solid, twist drills up to 1-1/4″ (31.75 mm) diameter, and its 9” stroke ensures versatility with longer tools.

Advanced Features:

  • Heavy-Duty 4-Speed Gearbox: Optimal for various drilling tasks.
  • 4” Diameter and 4” Depth of Cut: Handles extensive drilling requirements.
  • 9” Stroke: Facilitates the use of longer tools with ease.
  • Magnetic Power Adhesion Control (MPAC): Ensures safety by detecting adhesive force and preventing drill activation under insufficient adhesion.
  • Magnetic Field Shape Control (MFSC): Maximizes holding power on thin materials.
  • Energy Saving Base (ESB): Reduces excessive heat, enhancing electromagnet life by using only 50% power when not under load.
  • Automatic Motor Stop: Prevents motor damage by stopping automatically when brushes are worn out.
  • Semi-Automatic Gib Adjustment: Simplifies maintenance and operation.
  • Complete with Swarfshield: Provides added protection during drilling operations.

Equipped with the most advanced electromagnetic technology, the Steelmax D4 PRO ensures exceptional performance and durability. The Energy Saving Base (ESB) minimizes heat buildup, extending the life of the electromagnet, while the Magnetic Field Shape Control (MFSC) and Magnetic Power Adhesion Control (MPAC) systems provide maximum safety and efficiency. Choose the Steelmax D4 PRO for a reliable and powerful drilling solution.

Application Use Cases

The S14-M suits mechanical fabrication, transportation, and construction work where angled cuts matter as much as a clean edge. It handles pipe, plate, channel, conduit, angle iron, metal studs, rebar, and tubing, making it useful for structural steel fabrication, custom metal frames, and repeatable angle cuts on production runs. Its 1750W motor and portable 72 lb frame support both jobsite work and continuous shop use.

Frequently Asked Questions

The S14-M offers a wider +/-46° mitering range compared to the S14's 45°, plus a heavier cast-aluminum base for added stability. Both share the same 1750W motor, 14" blade, and pipe capacity, with the S14-M priced for its extra versatility.

The S14-M comes in both 120V/60Hz (SM-S-14-M) and 230V/50Hz (SM-S-14-M-230) versions, so it runs on standard shop power or 230V circuits depending on your facility's setup.

A newly designed 14" laser-cut TCT blade for mild steel is included. The 1" arbor bore accepts other compatible 14" blades, so operators can swap in one suited to aluminum, stainless, or thinner materials.

The S14-M miters up to +/-46°, letting operators dial in custom angles for fabrication layouts. The precision miter table locks at the set angle, delivering repeatable, accurate cuts across a production run.

At 72 lbs, the S14-M is portable enough for jobsite use while still built for shop duty. Steelmax positions it for both field and shop environments, making it a flexible pick either way.
