Product Description

 

This compact set replaces 28 individual drill bits with a 3-piece drill bit set of 

 

1/8"- 1/2", 3/16"- 1/2", and 1/4"- 3/4". The two-fluted design provides faster, 

 

smoother cutting.

 

Before drilling and screwing, the automatic center punch can be used to mark hole 

 

locations. It delivers an automatic, high-impact, spring-loaded strike when pressed 

 

against wood, metal, and plastic surfaces. An adjustable cap regulates the striking 

 

force. It features a heat-treated alloy steel punch with a sharp precision tip and a 

 

corrosion-resistant brass body with non-slip knurled grip.

 

Package included:

 

• 3 x  Step drill bit

• 1 x  Automatic center punch
