VEVOR 1100W Magnetic Drill Press 12000 N Magnet Force w/6 pcs HSS Annular Cutter Bits

1100W Copper Motor in the Magnetic Portable Drill Press for Controlled Steel Coring

This magnetic portable drill press features a 1100W copper-wound motor and a fixed spindle speed of 550 RPM, the lowest fixed speed in the VEVOR magnetic drill range. The lower surface speed at the cutting edge controls heat generation during coring passes, extending bit life and producing cleaner bore-wall geometry than higher-speed machines, which generate excess friction in larger-diameter cuts. 

For operators who drill structural steel with hollow-boring bits, the ability to control spindle speed is a quality advantage, not a limitation. Maximum coring diameter is 1.57 in / 40 mm, maximum boring depth is 2 in / 50 mm, and maximum travel distance per stroke is 4.92 in / 125 mm. This machine is designed to be used only with hollow-boring bits; annular cutters with pilot pins are incompatible with this spindle system. The unit is supplied with a 110V/60 Hz power supply.

Six-Piece HSS Coring Bit Set Covering 12 mm to 26 mm Diameter Range

The six-piece set of HSS annular cutter bits includes diameters of 12 mm, 16 mm, 18 mm, 20 mm, 24 mm, and 26 mm, covering the most common hole sizes used in structural steel connection work, equipment mounting, cable penetrations, and pipe flange applications. At purchase, the operator is presented with 6 specific sizes to choose from, allowing them to select the exact bit for the hole spec. They don’t have to pick the closest size and risk ending up with a hole that is too big or too small.

HSS construction provides each bit with sufficient hardness to be used repeatedly in mild steel and structural plate without the brittleness that makes carbide-tipped bits prone to chipping under the impact loads encountered when biting into harder material sections. The six-size progression is spaced to cover the practical range from small fastener clearance holes at 12 mm to mid-range structural holes at 26 mm. Operators can find compatible annular cutters without buying a separate chuck adapter, as they can use the standard 3/4 in Weldon shank interface for sizes outside this range.

12,000 N Two-Stage Electromagnetic Base for Job-Site Clamping on 110V Power

The two-stage electromagnetic base provides 12,000 N / 2700 lbs holding force on a solid iron surface to hold the machine against reaction forces generated during coring passes. Two-stage coil architecture amplifies magnetic field strength across two independent layers, generating a higher flux density at the base contact face than single-coil designs at equal current draw. That higher flux density is what lets the magnetic portable drill press machine hold steady at angles and inverted positions where gravity is fighting the magnetic hold.

Another important operating note from the spec data: Holding force decreases as workpiece steel thickness decreases. The effective clamping force is reduced below the rated value of 12,000 N because the thinner plate cannot be fully saturated with the magnetic field. Operators should always use a mechanical safety rope backup for inverted and horizontal drilling positions irrespective of plate thickness. They should check for sufficient plate thickness when working on thinner structural sections before relying on magnetic clamping alone. 

Magnetic Portable Drill Press with 350 ml Coolant Pot and Dustproof Ventilation

During each coring pass, the 350 ml stainless steel coolant pot delivers cutting fluid to the bore zone, reducing friction heat at the bit cutting edge and continuously flushing swarf out of the hole. HSS cutting edges get hot and lose hardness in a tiny fraction of the cycles you can expect with active cooling, so with the six-piece HSS bit set, regular coolant flow can dramatically prolong the life of each bit. The stainless steel pot resists corrosion by cutting fluids and prevents rust particles from contaminating the coolant supply.

The dustproof air inlet prevents metal swarf and airborne particles from entering the motor housing during operation, protecting the windings and bearings from premature motor failure caused by abrasive damage common in fabrication environments. Internal thermal management is supported by dedicated exhaust air channels that expel heat from the motor housing during high-load drilling cycles, supplementing the external coolant system. 

Rubber-Coated Three-Crank Feed System for Consistent Manual Bore Control

Three extended crank handles are each coated with non-slip rubber to help keep the operator's grip secure during manual feed, even when hands are wet from coolant splash or perspiration. At 550 RPM, the feed mechanism delivers a predictable, constant cutting torque, allowing the operator to apply even downward feed pressure without fighting sudden spikes in resistance. The combination of the low spindle speed and rubber-coated feed cranks allows the operator to have fine control over the penetration rate from the first bite to full depth.

Rubber coating also reduces vibration transmitted from the cutting area through the crank arms to the user's hands. Lower vibration in longer drilling times means less cumulative hand and wrist fatigue, which directly helps maintain more consistent feed pressure throughout the entire shift. Chatter marks in bore walls and cutting-edge wear are primarily caused by inconsistent feed pressure; maintaining consistent pressure through each stroke produces cleaner holes and longer bit life for the complete six-piece kit.

Weldon Shank Interface and Multi-Industry Application Compatibility

The hollow boring bits are held in place with flat-sided drive engagement in a 3/4 in / 19.05 mm Weldon shank toolholder, which prevents the bits from slipping rotationally under the torque loads applied during large-diameter coring in structural steel. With this standard shank size, several manufacturers sell hollow-boring bits. It allows the operator to purchase bits outside the 12-26 mm range without having to buy into a proprietary tooling system and to expand beyond the 6-piece set that comes with the tool.

This magnetic portable drill press weighs 30 lbs / 13.6 kg in total, making it light enough for one operator to move from work position to work position in shipbuilding, bridge construction, railway manufacturing, wind power generation, power plant construction, industrial fabrication, and equipment installation environments. With 110V compatibility, a full, ready-to-use bit set, and integrated cooling systems, this model is a self-contained platform that arrives on site and is ready for immediate, productive use across all these application areas.
