Value Collection 01378454 Size 45 Cobalt Drill Bit

Product Description

The VALUE COLLECTION 01378454 is a screw machine length cobalt drill bit designed for high-speed drilling in tough materials where standard high-speed steel falls short. Built to a heavy-duty grade, it features a 135-degree split point that reduces walking on entry and requires no center punch on most surfaces. At 0.0820 inches in diameter (wire size 45) with a 1.75-inch overall length, this short-body geometry gives it added rigidity for precision work in blind holes and tight setups. It cuts right-hand with a regular spiral flute pattern and ships bright and uncoated with a straw finish. Machinists, tool-and-die technicians, and maintenance professionals reach for this bit when drilling stainless, alloy steel, and similarly demanding workpiece materials.

This bit is suited for bench drilling, CNC machining centers, drill presses, and hand-held electric drills wherever short tool stick-out and maximum rigidity are priorities. The screw machine length body is a common choice for production environments and sheet metal applications where hole-to-hole consistency matters. The 0.75-inch flute length keeps chip clearance manageable in shallow-to-moderate depth passes on hard or work-hardening materials. It is sold individually but is subject to a minimum order quantity of 12 units, making it appropriate for shop stock replenishment or tooling kits.

Key Features

• Wire size 45 diameter at 0.0820 inches for precision small-diameter drilling
• 135-degree split point reduces thrust and eliminates the need for center punching on most materials
• Cobalt construction provides heat resistance for drilling stainless steel and hardened alloys
• Screw machine length body adds rigidity over jobber-length bits in the same diameter class
• Right-hand, regular spiral flute design for standard chip evacuation
• Heavy-duty grade rating for demanding production and maintenance applications

Compatibility

Designed as a straight-shank screw machine length drill bit compatible with standard drill chucks and collet holders accepting a shank at the 0.0820-inch diameter class. Suitable for use in drill presses, machining centers, and hand-held power drills equipped with appropriately sized chucks.

Installation Notes

A licensed machinist or trained technician should confirm proper chuck engagement and shank seating before operation. Always power down and de-energize the spindle before changing tooling. Cutting speeds and feeds should be selected based on workpiece material and machine capability — cobalt bits tolerate higher heat than HSS but still benefit from appropriate lubrication or coolant when drilling ferrous metals. Note that coolant-through is not supported on this bit.
