25/32 Drill Bits

A 5/32 drill bit is equal to 0.15625 inches, or approximately 3.97 mm, in diameter. It's a smaller fractional size commonly used for pilot holes, light-gauge metal, and general-purpose drilling where a compact bit diameter is required.

Our 25/32 drill bits are available in M35 Cobalt for superior heat resistance and durability in hard metals, or Black & Gold coated High Speed Steel (HSS) for reliable general-purpose drilling in metal, wood, and plastic.

Cobalt drill bits (M35) contain a cobalt alloy blend, offering greater heat resistance and durability for stainless steel and hard metals. Black & Gold bits use an oxide coating on HSS for added surface hardness, making them a cost-effective choice for general-purpose drilling.

Jobber length refers to a standard drill bit length ratio, offering a balance between rigidity and reach. It's the most common bit length for general-purpose and industrial drilling, suitable for a wide range of material thicknesses without excessive flex.

Yes, especially the M35 Cobalt version, which is specifically engineered for drilling stainless steel and other hard, heat-generating materials. The 135-degree split point also reduces walking and ensures accurate starts on tough surfaces.
