Diablo DBD070063701F 7 in.Metal Cut Off Disc – Type 27 (25-Pack)

Key Features

Cuts Metal Fast, Lasts Long The premium aluminum oxide blend cuts through steel, stainless, cast iron, and sheet metal faster than standard discs – and keeps cutting longer before it wears out. Type 27 Depressed Center The depressed center Type 27 profile gives you better access in tight spots and flush-cut capability that flat Type 1 wheels can’t match – especially useful around flanges and weld joints. 25-Pack Value Twenty-five discs per pack means you’re stocked for a full project run without constant reordering – lower per-disc cost and fewer supply runs.

Overview

The Diablo DBD070063701F is a 7-inch metal cut-off disc designed for use with 7-inch angle grinders. This is a Type 27 depressed center cut-off wheel built specifically for cutting steel, stainless steel, cast iron, and sheet metal. It comes in a 25-pack, making it the right call for contractors, fabricators, and metalworkers who go through discs regularly and want a premium abrasive at a sensible volume price.

Each disc measures 7 inches in diameter, 1/16 inch thick, with a 7/8-inch arbor. The 1/16-inch (1.6 mm) thickness is a thin-kerf profile – that means less material lost per cut, less heat buildup, and cleaner cuts through metal compared to thicker grinding wheels. The 7/8-inch arbor fits standard angle grinder spindles without adapters.

The abrasive compound is a premium aluminum oxide blend, which is the right grain for cutting ferrous and non-ferrous metals. Grit is rated at 36 – coarse enough to bite through metal aggressively while still leaving a workable cut edge. The formulation is specifically engineered for fast material removal and extended disc life, so you’re not burning through a disc every few cuts. Diablo manufactures this disc in Spain, which is consistent with the brand’s commitment to tighter tolerances and more consistent abrasive bonding than cheaper alternatives.

Fully reinforced construction means this disc won’t delaminate under load or at speed. Maximum rated speed is 8,450 RPM, which covers the operating range of most 7-inch angle grinders. The disc is built to OSHA and ANSI B7.1 standards – important if you’re on a regulated jobsite.

The Type 27 depressed center profile sets this disc apart from flat Type 1 wheels. The recessed hub allows you to cut closer to a surface or into tight corners where a flat disc would contact the workpiece before the cutting edge does. This is especially valuable when cutting structural steel, cutting off bolts near a surface, or working around welded joints where flat access is limited.

This 25-pack is the right buy for metal fabricators, ironworkers, pipefitters, HVAC mechanics, and contractors who run angle grinders regularly. If you’re cutting steel on the daily, buying in packs of 25 at Diablo’s quality level is simply the smarter move over grabbing single discs from a big box store.

Pro Tip

Let the disc do the work – apply steady, even feed pressure without forcing the cut. Pushing too hard generates excess heat, glazes the abrasive faster, and shortens disc life. At 1/16-inch thick, these discs cut clean and fast with minimal pressure, which is exactly how you get the most cuts per disc out of the 25-pack.

Tool Nut’s Take

Tool Nut’s Take

The Diablo DBD070063701F Is the Right Disc for Serious Metal Cutting

If you’re running a 7-inch grinder on metal regularly, this is the disc you want in your bag – and buying 25 at a time is just common sense.

• Who it’s for: Metal fabricators, ironworkers, pipefitters, HVAC mechanics, and contractors who cut steel, stainless, or cast iron frequently and need a disc that won’t quit halfway through a job.
• Why it stands out: Diablo’s premium aluminum oxide blend genuinely cuts faster and lasts longer than bargain-bin discs. Made in Spain, built to ANSI standards, and the Type 27 depressed center gives you access angles a flat wheel just can’t reach.
• Worth knowing: This is a 25-pack – the per-disc price is significantly lower than buying individually, but you do need a 7-inch angle grinder with a 7/8-inch arbor to run these. No adapter needed for most standard grinders.

Common Questions

• Can this disc be used on stainless steel? Yes. The Diablo DBD070063701F is rated for stainless steel, as well as standard steel, cast iron, and sheet metal.
• What is the maximum RPM for this disc? The maximum rated speed is 8,450 RPM. Always ensure your angle grinder’s operating RPM does not exceed this rating.
• What size angle grinder does this disc fit? This disc is designed for 7-inch angle grinders with a 7/8-inch arbor spindle. No adapter is required for standard grinders.
• What is the difference between a Type 27 and a Type 1 cut-off wheel? A Type 27 has a depressed (recessed) center hub, which allows you to cut closer to a surface and into tighter spaces. A Type 1 is flat all the way across and is better for straight, open cuts where clearance is not a concern.
• Can this disc be used for grinding, not just cutting? No. This is a cut-off disc, not a grinding disc. Using it for side grinding or heavy material removal can cause the disc to crack or shatter. Use a dedicated grinding wheel for grinding tasks.
