Value Collection 01-026 No. 26 Cobalt Jobber Drill Bit

Product Description

The VALUE COLLECTION 01-026 is a No. 26 wire-size jobber-length drill bit ground from cobalt high-speed steel for heavy-duty drilling applications. It measures 0.1470 inches in diameter with a 3-inch overall length and a 1.875-inch flute length. The 135-degree split-point geometry reduces walking on entry and lowers thrust force compared to standard 118-degree points. A straw finish indicates heat treatment and provides moderate surface hardness. Two right-hand spiral flutes evacuate chips efficiently during through-hole and blind-hole drilling. This bit is sold individually and suits machine-shop, maintenance, and field drilling tasks where wire-gauge sizing is specified.

This drill bit is designed primarily for drilling stainless steel and hardened materials — workpiece material codes M and S — where cobalt content provides the heat resistance and edge retention that standard high-speed steel cannot sustain. Typical applications include drilling fastener clearance holes, tapping prep holes, and general metalworking operations in fabrication shops, maintenance facilities, and industrial settings. The straight cylindrical shank seats in standard drill chucks on drill presses, CNC machining centers, and handheld power drills without requiring any special toolholding adapter.

Key Features

• Cobalt high-speed steel construction for heat resistance when drilling stainless steel and hardened materials
• 135-degree split-point tip reduces drill walk and lowers feed pressure on hard workpieces
• Straw coating indicates surface-hardened treatment for extended edge life
• 1.875-inch flute length supports a maximum drilling depth of 1.875 inches
• Regular right-hand spiral flutes with no coolant-through requirement for general-purpose use
• Straight cylindrical shank (0.1470 inches diameter) fits standard three-jaw drill chucks

Compatibility

Designed as a general-purpose jobber drill bit that seats in any standard drill chuck accepting a 0.1470-inch straight shank, including drill presses, lathes, and handheld power drills.

Installation Notes

Installation is performed by machinists, toolroom technicians, and maintenance mechanics. Secure the shank fully in the chuck before operation and verify the chuck key is removed prior to starting the spindle. When drilling stainless steel or hardened materials, use a low spindle speed and consistent feed pressure to prevent work hardening at the cut. Do not exceed the maximum drilling depth of 1.875 inches without retracting the bit to clear chips.
