Inland Hobby Products Information
Diamond Drilling Drums

The easy way to drill precision holes and create fine details while still using standard size drums!

Key Features:

• Drill precise 1/8" (3  mm), 1/4" (6 mm) or 3/8" (10 mm) holes.
• Works right on top of larger diamond drums, no need to change or remove before using.
• Standard 120Grit for multi-task use.
• Like all Inland bits, the brass cores are manufactured on "Swiss precision" machinery for consistent and accurate tolerances. Bits are measured for true before the diamond is applied, so the bits spin properly on the motor shaft.
