4 GEERAL IFORMATIO Drilling guide. Recommendations for use. Ensure workpiece is irmly and securely fastened. Avoid excess lateral loads. Ensure collets and drill chucks are in good condition and will not allow drill slippage. Both drill and component damage can occur. When using taper shank drills ensure all taper sleeves are clean and in good condition. ever allow the drill to drive off the tang. This is an indication that either the drill, the sleeve, or both are damaged. Use only soft faced hammers to drive the taper shank into the sleeve. Use a proper drift key to remove the shank from the sleeve. Ensure drill is kept sharp, and sharpen before point of failure. If allowed to become blunt extra grinding will be needed to bring the drill back to optimum performance. Keep the lutes free from swarf. Clogged lutes will hamper drill performance. Use adequate coolant, particularly at the drill point. Avoid excessive speed and feed rates. Use the charts in this catalogue. If unsure of the correct speed or feed rate to use, it is generally better to start at low speeds and feeds, and build up as appropriate. When resharpening it is important that all wear is removed, and the correct point geometry is maintained. Do not overheat or burn the drill when grinding. Ensure correct drill is chosen for application and material type, particularly with deeper holes to avoid pecking where possible. Reaming guide. Recommendations for use. Ensure workpiece is irmly and securely fastened. Bending and moving may break reamer. When using taper shank reamers ensure all taper sleeves are clean and in good condition. Reamers must be kept sharp. As reamers only cut on the bevel lead, only the bevel, and the taper lead in the case of hand reamers, require regrinding. A blunt reamer wears on the outer corners on the bevel lead, resulting in a poor inish, undersized holes and increased torque. When reaming, ensure that swarf is not allowed to build up in the lutes. Adequate lubricant must be directed to the cutting area. When reaming high tensile materials, an improved inish can be acheived by using chlorinated or sulphurised oils. The correct amount of stock must be left in the hole after drilling or coring to obtain the required hole size and inish, and eliminate excessive reamer wear. If too little stock is left for removal by reaming the reamer will rub in the hole giving rise to premature wear and loss of size. The table below shows approximate amounts of stock to be removed by reaming. This is for guidance only, as the amount of stock to be left depends greatly on the type of material being reamed and the type of reamer used. When hand reaming, leave approximately two thirds of machine reaming allowance. Stock removal. Amount of material to be left in prior to reaming.
