Value Collection 01188291 No. 29 Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 01188291 is a No. 29 wire-size jobber-length drill bit designed for general-purpose drilling in steel and cast iron. Built from high speed steel (HSS) with an oxide coating for added lubricity and corrosion resistance, this bit cuts at 0.1360 inches in diameter with a 118-degree standard point angle. The two-flute, right-hand spiral design clears chips efficiently during through-hole and blind-hole operations. At 2.875 inches overall length with a 1.75-inch flute length, it fits standard drill chucks without modification. Machinists, maintenance technicians, and fabricators rely on this size for tapping pilot holes and precision hole work in ferrous materials.

This jobber drill bit is suited for drilling steel and cast iron in light to medium-duty shop and field applications. The straight cylindrical shank seats securely in keyed or keyless chucks on benchtop drill presses, hand drills, and CNC turret machines. The web-thinned, tapered-web construction reduces thrust force at the point, making it practical for hand-held drilling where feed control matters. The regular spiral flute geometry is well matched to ferrous workpieces at moderate spindle speeds.

Key Features

• No. 29 wire size, 0.1360-inch diameter — common pilot size for 8-32 tapping operations
• 118-degree standard point angle with web-thinned, tapered-web tip for reduced entry thrust
• High speed steel construction for durability in steel and cast iron
• Oxide coating improves lubricity and provides basic corrosion protection
• Right-hand, regular spiral flute with 1.75-inch flute length for efficient chip evacuation
• Straight cylindrical shank, 0.1360-inch diameter, compatible with standard drill chucks

Compatibility

Designed as an OEM-style general-purpose jobber drill bit for use in standard keyed and keyless drill chucks that accept straight-cylindrical shanks in the 0.1360-inch diameter range. Primary workpiece materials are steel and cast iron.

Installation Notes

Install and remove this bit only with the drill or press powered off and the chuck fully released. Secure the straight shank fully into the chuck jaws before tightening to prevent runout. Use appropriate cutting fluid when drilling steel to extend bit life and maintain hole quality. Follow applicable shop safety standards for eye protection and workpiece clamping during all drilling operations.
