Cleveland C11701 Jobber Drill Bit 47 Hss 135 Split Point

Product Description

The CLEVELAND C11701 is a wire gauge size 47 jobber length drill bit designed for precision hole drilling in aluminum and similar non-ferrous materials. Built from high speed steel with a bright uncoated finish, this bit measures 2 inches overall length with a 1-inch spiral flute. The 135-degree split point reduces walking on entry and lowers thrust force, making it a reliable choice for production drilling and maintenance work. A tapered web with web thinning further improves chip evacuation and cutting efficiency. Licensed HVAC, plumbing, and electrical tradespeople frequently use wire gauge bits like this for panel knockouts, conduit work, and bracket fabrication.

The C11701 is suited for drilling aluminum as its primary workpiece material, and performs well in other soft metals and plastics under appropriate feed and speed conditions. The straight-cylindrical shank accepts standard three-jaw chucks on hand drills, drill presses, and CNC machining centers. With a 1-inch shank length and 0.0785-inch diameter, this bit fits tight-clearance applications where standard fractional sizes do not match the required hole specification. It conforms to NAS 907 Type B standards, making it a valid choice for aerospace-adjacent and heavy-duty trade applications.

Key Features

• Wire gauge size 47 with 0.0785-inch decimal diameter for precise hole sizing
• 135-degree split point reduces drill walking and entry thrust
• Web-thinned tapered web improves chip clearance and cutting efficiency
• High speed steel construction for durability in aluminum and soft metals
• Bright uncoated finish allows easy visual inspection for wear
• Meets NAS 907 Type B standard for heavy-duty grade applications

Compatibility

Designed as an OEM-style jobber length drill bit for use in standard three-jaw chucks and collet systems accepting a 0.0785-inch straight-cylindrical shank. Primary workpiece material is aluminum per manufacturer specification.

Installation Notes

This bit is installed by a machinist, electrician, plumber, or HVAC technician using any drill press, hand drill, or CNC spindle with a compatible chuck. Ensure the workpiece is securely clamped before drilling to prevent rotation and bit breakage. Use appropriate cutting fluid or lubrication when drilling metal to extend bit life and maintain hole tolerance. Disconnect power to any drill press or CNC machine before changing bits.
