Description
The Irwin 3/32″ x 2-1/4″ Black Oxide HSS 135 Degree Drill Bit (63506) is a general-purpose drilling solution engineered for accuracy and longevity. Made from high-speed steel with a protective black oxide finish, this bit is designed to handle a variety of materials including wood, metal, and plastic. The key feature is its 135-degree split-point tip, which allows the bit to start drilling immediately on contact, preventing it from “walking” or slipping on the surface. This self-centering design eliminates the need for a center punch and reduces the pressure required to start a hole. The black oxide coating not only provides excellent corrosion resistance but also helps to reduce friction, contributing to a longer tool life. With its straight shank and jobber length, this drill bit is a versatile and reliable addition to any toolkit, from a professional workshop to a home DIY setup. It provides a clean, precise drilling experience, making it a go-to choice for countless projects.
KEY FEATURES AND BENEFITS:
- Precision Drilling: The 135-degree split-point tip provides a self-centering start, eliminating the common issue of the bit “walking” and ensuring your hole begins exactly where you intend. This leads to cleaner, more accurate results.
- Corrosion Resistance: Coated with a black oxide finish, this drill bit is well-protected against rust and corrosion, extending its useful life and maintaining its performance over time, even in challenging environments.
- Versatile Use: Manufactured with high-speed steel (HSS), this bit is a great choice for drilling a variety of materials, including wood, plastic, and metal, making it a multi-purpose tool for many different applications.
- Reduced Drilling Effort: The 135-degree split point requires less force to start drilling, making the job easier and more efficient, especially when drilling into harder materials.

HOW TO USE:
- Secure the material: Clamp the material you are drilling firmly to a workbench or hold it securely to prevent it from moving during drilling.
- Mark the spot: Use a pencil or marker to clearly indicate the precise location where you want to drill the hole.
- Insert the bit: Insert the drill bit into the chuck of your drill and tighten it securely. Ensure the bit is centered and held firmly.
- Position the drill: Place the tip of the bit directly on the marked spot. The 135-degree split point will help to keep the bit centered.
- Drill the hole: Start the drill at a slow speed and apply steady, consistent pressure. Once the bit has started to bite, you can increase the speed.
- Clear chips: Periodically withdraw the bit from the hole to clear chips and debris, especially when drilling into metal, to prevent overheating and ensure a clean cut.
BENEFITS OF USING IRWIN 3/32″ X 2-1/4″ BLACK OXIDE HSS 135 DEGREE DRILL BIT (63506):
