This document discusses various methods for securely holding workpieces on a drill press to prevent damage and ensure safety. It describes the use of vises, vee-blocks, step blocks, angle plates, hand vices, drill jigs, and strap clamps to clamp round, square, odd-shaped, and sheet metal pieces in a stable position for drilling holes in production quantities or one-off jobs. Secure clamping of workpieces is essential on a drill press to hold the material steady during the drilling operation.

1. Work Holding on the Drill
Press

2. Method of holding Work
 There are several methods of holding work
on the drill press in order to prevent damage
to the work and to the operator.

3. NEVER HOLD
WORK BY HAND

4. Machine Vise
 Drill Press Vise
 Used to hold round, square or odd-shaped rectangular pieces
 Clamp vise to table for stability

5. Machine Vice
 Angle vise
 Angular adjustment on base to allow operator to drill holes at an angle
without tilting table

6. VEE-BLOCKS
 V-blocks
 Made of cast iron or hardened steel
 Used in pairs to support round work for drilling

7. STEP BLOCKS
 Step blocks
 Used to provide support for outer end of strap clamps

8. Direct Clamping
Clamping set

9. ANGLE PLATE
 Angle plate
 L-shaped piece of cast iron or hardened steel machined to accurate 90º
may be bolted or clamped to table

10. Hand Vice
 used on drilling
machine to clamp
sheet metal

11. DRILL JIGS
 Drill jigs
 Used in production for drilling holes in large number of identical parts
 Eliminate need for laying out a hole location

12. STRAPS CLAMP
 Clamps or straps
 Used to fasten work to table or angle plate for drilling
 Usually supported at end by step block and bolted to table by T-bolt
that fits into table T-slot
