Bosch Cordless drill with hammer function set

A “drill with hammer function set” is a fantastic investment for anyone who needs to drill into tough materials like concrete, brick, or stone, in addition to standard drilling in wood, metal, and plastic. The “set” typically means you’re getting a complete package ready to go.

Here’s a breakdown of what that usually entails and what to look for:

What is a Drill with Hammer Function (Hammer Drill / Combi Drill)?

Unlike a standard drill that only rotates, a hammer drill (often called a “combi drill” in some regions) adds a rapid percussive or hammering action along the axis of the drill bit. This action, combined with the rotation, pulverizes hard materials, allowing the drill bit to penetrate much more effectively and quickly than a regular drill.

Most hammer drills have a selectable mode switch:

• Drill (or Drill/Driver) Mode: Rotation only, for drilling into wood, metal, plastic, and for driving screws.
• Hammer Drill Mode: Rotation combined with the hammering action, specifically for masonry.

Why a “Set”? What’s Included?

A “set” typically bundles the essential components you need to start working:

1. The Hammer Drill: The main tool itself, with the selectable drill and hammer drill modes.
2. Batteries (for Cordless Sets):
   • At least two Lithium-Ion (Li-Ion) batteries are ideal. This allows you to have one battery on charge while you’re using the other, minimizing downtime.
   • Voltage: Common cordless hammer drills are 18V (or 20V MAX in North America). Higher voltage options (24V, 36V, 60V MAX, etc.) exist for more demanding applications.
   • Capacity (Ah – Amp-hours): This dictates runtime. Common capacities for 18V systems are 2.0Ah, 3.0Ah, 4.0Ah, or 5.0Ah. A higher Ah means longer work time per charge.
3. Charger: To recharge the batteries. Fast chargers are a plus.
4. Carry Case/Bag: For organized storage and protection of the tool and accessories.
5. Accessories (often included, especially in larger sets):
   • Masonry Drill Bits: Essential for drilling into concrete, brick, and stone. Look for carbide-tipped bits.
   • Wood Drill Bits: For various diameters in wood.
   • Metal/HSS (High-Speed Steel) Drill Bits: For drilling into metals.
   • Screwdriver Bits: Various types (Phillips, flathead, Torx, square drive) to cover different fasteners.
   • Cordless drill
