OXTUL 12-Piece 1/4in Twist Drill Bits – Black & Gold, HSS M2, 135°

Overview

Meet the OXTUL 12-piece drill bit set, built for precision and durability. Crafted from M2 high-speed steel and finished in a distinctive black and gold coat, these bits are designed to deliver consistent performance across metal, wood, and plastics. The set includes 12 pieces with a 1/4 inch diameter, total length 4 inches, and a usable length around 2.75 inches, neatly housed in a plastic bag for easy transport.

Why choose these drill bits

The 135-degree tip is designed to start precisely and reduce wandering, while a twist design clears chips as you work. The 3-flat shank helps prevent slipping in the chuck for stable drilling. The bright finish not only looks premium but also helps you quickly assess wear in busy workshops.

Key features

• Durable M2 high-speed steel with a bright coating for reliable performance.
• Hardness around HRC 62–63 to keep edges sharp under typical metal, wood, and plastic tasks.
• Diameter 1/4 inch; total length 4 inches; working length about 2.75 inches; 12-piece pack in a resealable bag.
• 3-flat shank for a secure fit; suitable for metal, wood, and plastics; not recommended for concrete, masonry, or stainless steel.
• 135-degree tip with twist geometry for faster cuts and self-centering starts; efficient chip clearance for cleaner holes.

Practical use scenarios

In a home workshop, you may be mounting hardware to aluminum frames, drilling through thin steel brackets, or crafting wooden trim for a project cabinet. The bits are designed to deliver consistent starts and smooth exits, with less wandering and fewer re-drills. The self-centering nature helps you stay on the intended line, while the chip-clearing flutes minimize debris buildup.

Care and handling

To maximize life, work at sensible speeds, avoid forcing the drill, and keep the bits cool. Following the Not For Use On guidance helps prevent premature wear. When not in use, store in the included bag to protect the sharp edges from nicks and corrosion.

Tips for best results

• Cool the bit during drilling to extend life.
• Use appropriate feeds to minimize heat buildup.
• Avoid using on concrete, masonry, or stainless steel.
