Walter 01E118 SST 29-Piece Jobber Drill Bit Set: 1/16" – 1/2"

Drill faster, cleaner, and longer in the toughest materials.

The Walter 01E118 SST (Super Stainless Tooling) drill bit set is engineered for professionals who can’t afford downtime. Whether you are drilling through stainless steel, high-tensile alloys, or general-purpose carbon steel, these bits are designed to stay sharp where others dull. Featuring the innovative Quickshank design, these bits eliminate chuck slippage, ensuring maximum power transfer from your drill to the workpiece.

Why the Walter SST Set Outperforms the Competition:

• Superior Heat Resistance: Crafted with a special cobalt-blend high-speed steel (HSS) to maintain a sharp cutting edge even under extreme friction.
• 118° Self-Centering Point: Prevents "walking" on curved surfaces and ensures immediate penetration without the need for a center punch.
• Quickshank Technology: The three-flat shank design provides a non-slip grip in all standard keyless and keyed chucks.
• Precision Increments: Includes 29 pieces ranging from 1/16" to 1/2" by 64ths, ensuring you always have the exact diameter required for tight-tolerance projects.
• Rugged Storage: Comes in a heavy-duty, labeled metal index case for easy organization and long-term protection on the job site.

Technical Specifications

Pro Tip: For maximum tool life when drilling stainless steel, use these bits with Walter Alucut™ or CB-100™ cutting lubricants to reduce heat buildup and increase drilling speed.

Frequently Asked Questions (FAQ)

Q: Can these bits be used on materials other than stainless steel? A: Absolutely. While the SST (Super Stainless Tooling) series is engineered specifically for the extreme heat and work-hardening properties of stainless steel, they perform exceptionally well on mild steel, cast iron, and non-ferrous metals like aluminum or brass.

Q: What is the advantage of the 118° point over a 135° point? A: The 118° point is the "gold standard" for general-purpose and stainless drilling. It provides a sharper angle that penetrates more easily into tougher materials without needing as much feed pressure, which helps prevent the material from hardening before the hole is finished.

Q: Will the Quickshank fit in a standard 3/8" or 1/2" drill chuck? A: Yes. The Quickshank features three precision-ground flats on the shank. This design is compatible with all standard keyed and keyless chucks. It specifically prevents the bit from spinning or "slipping" in the chuck when you hit a high-torque snag.

Q: Are these bits cobalt or high-speed steel (HSS)? A: Walter SST bits are manufactured from a premium, cobalt-enriched high-speed steel. This blend offers the perfect balance: the heat resistance of cobalt for hard metals and the durability of HSS to prevent the brittleness often found in 100% cobalt bits.

Q: Can these drill bits be sharpened? A: Yes. Because they are solid SST material throughout (not just a surface coating), you can regrind and sharpen these bits multiple times to extend their service life.

Q: What sizes are included in this 29-piece set? A: This set includes every size from 1/16" to 1/2" in 1/64" increments. This provides a comprehensive range for professional fabrication, ensuring you never have to "make do" with a size that is slightly off.
