3 Pcs Step Drill Bits Set Cobalt & HSS - Impact Ready 1/4 in Hex Shank

In this review the 3 Pcs Step Drill Bits Set from METOTY is assessed for tradespeople and serious DIYers who need a compact, durable solution for enlarging and chamfering holes in metal and softer materials. The main reason to consider this kit is its combination of M35 high-speed steel with cobalt elements and titanium coating, which promises longer life and the ability to tackle hardened steel while remaining impact ready with a 1/4 in hex shank. It is a good match for users who want fewer bit changes and faster drilling with a reliable connection to cordless impact drivers.

Key Features

• Three versatile step sizes: The set covers ranges from 1/8 in to 7/8 in across three bits so users can drill many hole sizes with a single bit instead of swapping multiple bits.
• 4-flute fast cutting: The four-flute design reduces cutting time and improves chip removal, delivering up to twice the drilling speed in many thin and medium materials.
• M35 HSS with cobalt and titanium coating: Materials and coating provide enhanced wear resistance and strength for drilling through tough metals and extending service life.
• 1/4 in hex impact shank: The hex shank creates a secure, stable connection to impact drivers and cordless drills for high-torque applications.
• Includes chamfering tool: The extra chamfering tool smooths hole edges after drilling, saving a finishing step and improving fit for fasteners.

Who It's For

The kit suits professional handymen, sheet metal workers, and committed DIYers who frequently drill a range of hole sizes in metal, stainless steel, aluminum, wood, and plastic and want a compact set that reduces bit changes. Its construction is aimed at users who run impact drivers and need bits that resist wear when hitting harder materials.

Less suitable are users who only drill a single fixed hole diameter often enough to justify a large solid drill bit set, or those needing specialty coatings or diameter tolerances for precision aerospace or optics work; for those tasks a dedicated precision bit would be preferable.

Pros & Cons

Pros

• Durable M35 HSS with cobalt elements and titanium coating gives better wear resistance for tougher metals.
• Step design and included chamfer tool reduce the number of bits required and speed finishing work.
• 1/4 in hex shank is impact ready, improving stability in cordless drivers under load.
• Four flutes improve cutting speed and chip evacuation for more efficient drilling.

Cons

• Step bits are less suited for high-precision hole tolerances where a dedicated single-diameter bit is required.
• Not intended to replace large drill bit sets for users who need many discrete diameters beyond the provided ranges.
