OVERVIEW

Maximize Shop Productivity with Walter SST+ Drill Bits

In any industrial maintenance or fabrication shop, the cost of downtime caused by broken or dull tooling can quickly outpace the cost of the consumables themselves. The Walter #12 SST+ Jobber Drill Bit is engineered to address this specific challenge, offering a robust solution for high-volume drilling operations. Manufactured with a specialized cobalt blend, these bits are designed to withstand the high thermal stresses generated during continuous drilling, ensuring they maintain their cutting edge far longer than standard high-speed steel alternatives.

For procurement managers and shop foremen, the SST+ series represents a smart investment in efficiency. The unique Bronze SST surface treatment acts as a lubricant and heat shield, drastically reducing friction. This means your team spends less time changing out burnt bits and more time on fabrication. The bit features a "High Flow" flute design which rapidly evacuates chips; this is critical for preventing the heat buildup that destroys lesser bits. By choosing Walter SST+, you are equipping your facility with tools that deliver consistent performance, hole after hole.

Versatility is key in MRO environments. This #12 jobber drill is capable of handling a wide array of materials found in typical shops, including mild steel, aluminum, and difficult-to-machine stainless steel. The back-tapered body design further reduces the risk of binding, which is a common cause of tool breakage and operator injury. Stocking your tool crib with Walter SST+ bits ensures your workforce has the reliable, high-performance tooling necessary to meet tight production deadlines without interruption.

FAQ

A #12 wire gauge drill bit has a diameter of approximately 0.1890 inches (4.80 mm).

Yes, the Walter SST+ is made with a cobalt blend specifically designed to handle the heat and hardness of stainless steel grades like 304 and 316.

No, the self-centering Speed Tip allows you to start drilling immediately without walking, even on round surfaces, eliminating the need for center punching.

The Bronze SST surface treatment reduces friction between the bit and the workpiece, which lowers heat generation and extends the life of the cutting edge.

Yes, the high-flow flute design is excellent for aluminum as it quickly evacuates the soft, gummy chips that typically clog standard drill bits.

Jobber length is the standard length for general-purpose drilling, offering a balance of reach and rigidity. Mechanics length is shorter and more rigid but has less reach. This product is a Jobber length bit.

These bits are typically sold individually or in small packs. Please check the specific quantity selector on the product page for bulk ordering options.

The back taper is very slight and is designed to prevent the shank from binding in the hole as you drill deeper; it does not affect the accuracy of the hole diameter at the tip.
