BLACK & WHITE TITANIUM COATED STEP DRILL BIT SET – 5 PIECE

Cover 23 distinct hole sizes from 1/8" through 1-3/8" with one professional 5-piece Black & White step drill bit set. With 6-step, 9-step, 10-step, 12-step, and 13-step bits, this set gives fabricators, electricians, maintenance crews, automotive technicians, and general shop users broad hole-size coverage without relying on a large collection of conventional drill bits. The alternating Black & White step colors make each cutting diameter clearly visible while drilling, so you can easily track your progress and know exactly where you are in the drilling process.

Each bit is built from M2 high-speed steel with a titanium coating for durable cutting performance in demanding drilling applications. Self-centering split points help reduce walking at startup, while spiral double-flute geometry promotes fast chip evacuation and helps manage heat during drilling. Combined with the high-contrast step design, the progressive profiles make it easier to drill and enlarge holes accurately to the required diameter while reducing repeated bit changes.

Machine Compatibility

Machine compatibility varies by the individual bit in this set.

The 9-step, 12-step and 13-step bits have 1/4" quick-change shanks for compatible drill chucks and impact drivers. The 10-step bit uses a 3-flat shank for an adjustable drill chuck; check the 6-step bit’s shank before choosing a tool.

Compatible examples include:

• Corded drills
• Cordless drill/drivers
• Rotary drills
• Compatible 1/4" quick-change impact drivers for applicable bits
• Drill presses
• Pillar drilling machines
• DEWALT® DCD800 — drill/driver for the quick-change bits
• Makita® XFD14Z — drill/driver for the quick-change bits
• Milwaukee® 2953-20 — impact driver for the quick-change bits
• DEWALT® DCF845 — impact driver for the quick-change bits

Other compatible models can also be used. Match the tool’s drilling capacity and speed to your material and hole size; use an adjustable chuck for the 10-step bit.

Safety Tips

• Wear eye protection and appropriate hearing and respiratory protection. Keep gloves and loose clothing away from rotating parts.
• Secure or clamp the workpiece before drilling.
• Select the bit that includes the required finished hole diameter.
• Keep the bit approximately 90° to the work surface for a controlled cut.
• Use the contrasting Black & White steps to monitor drilling progress and stop at the required diameter.
• Progress through the steps gradually rather than forcing the bit.
• Use steady pressure and allow the cutting edges to do the work.
• Select drilling speed according to the workpiece material and cutting diameter.
• Larger hole diameters generally require slower, more controlled operation.
• Use an appropriate cutting lubricant when drilling metals.
• Stop the tool before clearing chips; use a brush, not your hands.
• Do not use hammer action when drilling with a hammer drill/driver.
• Make sure each shank is fully seated and securely retained before operation.
