Hillman 48604 Power Pro Premium Exterior Wood Screw, 10 X 4-Inch, 52 Pack, 10" x 4"

Drill America Cobalt Aircraft Extension Drills are similar to high-speed steel, but with more cobalt for improved performance when cutting harder metals such as stainless steel or nickel alloys. Gold oxide is a thinner oxide surface treatment than black oxide typically used to identify cobalt steel tools; performance is similar to uncoated tools. Drill America Aircraft Extension Drills are manufactured to National Aerospace Standard 907. The 135Â° split point is self-centering and reduces thrust. Sizes smaller than 1/16 in. have the 118Â° standard point. Drill America Aircraft Extension Drills are available in 6 in. and 12 in. overall lengths when extra reach is required.

Effective in drilling tough, high tensile strength materials like stainless steel, inconel and titanium
135° split point tip prevents drill from walking
Round shanks allow use with a wide variety of tool holding systems
