Alloy Magnetic Drill Kit – 35mm/50mm Depth Annular Cutters with Core Drill Bits & Drill Bits for Steel Plate

Key Features

• Magnetic Drill Compatibility: Universal shank design fits most magnetic drills for seamless steel plate and rail drilling.

• Efficient Chip Removal: Spiral flute design and staggered teeth ensure smooth chip evacuation, minimizing jamming in overlapping or cross holes.

• Multi-Purpose Kit: Includes 35mm/50mm annular cutters, core drill bits, and railway-specific drill bits for structural steel, bridges, and railroad maintenance.

• Coolant-Ready Design: Internal coolant channels reduce heat buildup, extending tool life in high-intensity operations.

Product Description

The annular cutters (core drill bits) remove material only from the perimeter, reducing power consumption and producing clean, burr-free holes. Their staggered tooth geometry prevents vibration, even in uneven surfaces, while the drill bits are reinforced with shock-resistant alloy tips for drilling hardened rails without chipping.

• Drill Bit Types:

• The core bit is a special steel structure drill bit. It is applicable to all kinds of magnetic drill, bench drill, radial drill machine(with the taper-shank arbor).It is welded by the imported high-strength carbide blade, the cutting edge consists of the outer edge, the blade, the inner edge, each cutting edge in the cutting process undertakes 1/3 cutting work, so that it is not easy to produce flaking. It has cutting edges in every blade, so in very short time to complete the drilling operation and get cross holes.

·Superhard alloy with high intensity and good wear resistance.

 Material: Hard alloy, HSS

Diameter: 12-100mm

Cutting Depth: 25/35/50/75/100mm

Shank diameter: 19/32mm

It is applicable to all kinds of magnetic drill, bench drill, radial drill machine, non-standard size is also accepted.

Advantages: The drilling speed is faster than ordinary drill over 7 times, drilling smooth, stable and no burr.
