AMBER & BLACK TITANIUM COATED STEP DRILL BIT 1/4"–1" – 13 STEPS

Create 13 clean, precise hole sizes from 1/4" through 1" with a premium M2 high-speed steel step drill engineered for demanding professional and heavy-maintenance work. The Amber & Black design combines premium construction with a dual-color step system that makes each cutting diameter easier to see while drilling, helping the operator track progress and stop accurately at the desired size. With closely spaced steps through a full 1" diameter, this bit delivers broad hole-size coverage while eliminating repeated changes between conventional drill bits.

The Amber & Black titanium coating is designed to provide a cooler cut for extended bit life, while the spiral double-flute geometry quickly evacuates chips and helps manage heat during the cut. A self-centering split point minimizes walking for faster, more controlled starts, and the stepped profile drills and reams in one smooth progression. The result is a premium step drill built around visibility, control, chip removal, and durability for drilling and enlarging holes in thin materials.

Use an adjustable drill chuck that securely grips the 3-flat shank, and match the tool’s capacity and speed to the hole size and material.

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.
• Keep the bit approximately 90° to the work surface for a controlled cut.
• 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 material and cutting diameter.
• Larger cutting 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 the 3-flat shank is fully seated and securely tightened in the drill chuck before operation.
