ECONOMY TITANIUM COATED STEP DRILL BIT SET – 5 PIECE

Benchmark Abrasives Economy TiN Coated Step Drill Bit Set – 5 Piece includes five of our best selling step drill bits covering a total of 23 different hole sizes.  These bits are ideal for making burr-free holes in aluminum, wood, copper, plastic, and sheet metal.  The Titanium Nitride coated HSS Step Drill Bits are suitable for home light maintenance work and feature a spiral double flute design that provides longer life and better chip removal and a self-centering split point to prevent wobbling. These drill bits are optimized for impact driver usage.

Step Drill Bits are ideal for drilling clean, precise holes in metal up to 1/4" thick. Engineered specifically for thin materials like sheet metal, these bits drill and ream to size in one motion—no need to switch out bits for different diameters. As the bit advances, each step gradually enlarges the hole to the next size. Titanium-coated Step Drill Bits offer enhanced cutting speed, superior durability, and self-centering action that reduces walking on the material. With just one bit, you can create multiple hole sizes efficiently and consistently.

Safety Tips/techniques:

• Always wear proper PPE to include (but not limited to) safety glasses, hearing protection, respirator, and hand protection.  Keep all guards in place on your machine.
  
• For best results bring the step bit to the workpiece keeping a 90 degree angle between the cutting surface and the cutting head. Using the tool at steeper angles (for example 45 degrees), could apply excess pressure on the head and snap the shank.
